This guide is undergoing updates, updates will be as following:

• adding teamwork/stragety section (I should really start on that section already)
• adding jungle section

Hello everyone I’m AkaiSwift and this is my Cho'Gath. I worked hard on this build and appreciate any feedback. Also I implore to reconsider any down votes until you've actually tried my build. It has the ability to both, defend your team mates and towers and to deal high damage. Further in this guide I’ll help you about how to play cho'gath little by little. so here's what i'm going to do in this guide: i'll divide the chapters with a divider every chapter is gonna have 4 subjects: tank , ability power, jungle and AP tank Enjoy the guide. Already thanks for reading this Cho'Gath build.

+ Ranged champion + Powerful burst attacks + Huge HP bonus with Feast + Feast true damage + Amazing slow with Rupture + Rylai's Crystal Scepter + Counter strike mages by silencing them with Feral Scream + Quick minions farming with Vorpal Spikes + Use able in much ways

SPACE

- Early game mana trouble - Early game squishy - Needs Feast stacks to be powerfull tank - Walks slow - When Feast maximum stack, big and obvious target . . . .

I can understand you don't want to have 3 pages of Cho'Gath runes, if you go playing Cho'Gath but sometimes you play tank some times AP and sometimes AP tank then I'd recommend using this rune page

• Greater Quintessence of Health:Useful in early game and when not stacked, most of my HP comes from Feast with a extra bonus from Rylai's Crystal Scepter. Late game you'll probably have those items but in early game you won't so then this rune gives you more of that early game tank status.
• Greater Seal of Armor:More survivability against AD DPS-ers and also helps for that early game tank status.
• Greater Glyph of Magic Resist:More survivability against AP DPS-ers and also helps for that early game tank status.
• Greater Mark of Magic Penetration: It makes sure your abilities do more damage and since my item build does not contain any magic penetration items this is most useful. Of course you won't need it with Feast, but the burst combination attack of Rupture Feral Scream and Feast with this rune it will do greater damage. I'll give more explanation of the use of this combination later on.

• Greater Quintessence of Health:Well of course for this early game survivability, since you're the tank they'll target you first and from level 6 they'll really start focusing on you because they don't want you to get too much Feast stacks.
• Greater Seal of Armor:More survivability against AD DPS-ers and also helps for that early game tank status.
• Greater Glyph of Magic Resist:More survivability against AP DPS-ers and also helps for that early game tank status. (Well those last 2 should sound really familiar by now, sorry for the repeating but it's just to explain the choice.)
• Greater Mark of Health:It was quite hard to figure out what rune to place here aiming for primary and defense in the end it became Greater Mark of Health as you noticed of course. The reason I chose this 1 is the same as with Greater Quintessence of Health.

• Greater Quintessence of Ability Power:Well it's quite obviously why I've chosen this rune I guess, the early game damage and for in late game that little bit extra damage. I'd get this rune and Greater Mark of Magic Penetration as first, because of the fact that with your Vorpal Spikes deal extra AP damage.
• Greater Seal of Replenishment:I've chosen this rune for it's mana regeneration what you'll really need as an AP Cho'Gath because early game you'll run out of mana very quickly.
• Greater Glyph of Mana:Hello mana bonus, of course the same reason as with the greater seal of replenishment. I guess i've repeated it enough now you have mana trouble in begin and as and AP mage we cant have that.
• Greater Mark of Magic Penetration:Well magic penetration you won't really need it with Feast but it empowers the other skills and since you'll be in trouble if the enemy tank is going to be smart *** and take much magic resistance we can better take some magic penetration.

• Greater Mark of Magic Penetration: Magic penetration guess I've explained this enough times
• Greater Glyph of Cooldown Reduction: Cool down reduction. Getting your Feast max in least time possible is a must
• geater seal of resilience: Armor for the tank status and early game survivability in jungle.
• Greater Quintessence of Ability Power: Ability power, makes your Vorpal Spikes stronger early game

Teleport:Even though you put out quite a damage, don't forget you're a tank! Whenever a ally needs you or a tower is about the get crushed you need to be there as quick a possible. It helped me a lot of times, whenever an ally really needs help and pings for it, you target for a minion in the direction he's heading/fleeing to and tank the hell out of the chaser. Also when your allies got ganked in, for example, top lane you just Teleport straight to tower, this will cause most of the times the enemy to flee and gives you possibility to save your tower. Also it can help you return to your own tower quickly after you've recalled or helped out other lane.

SPACE

Exhaust:This skill will help you a lot because Cho'Gath isn't the fastest champion. It can help you when chasing and fleeing, when chasing this can help because the slow of Rupture has a delay what gives the enemy the chance to run out of its range with Exhaust you can easily get him into range so you can slow him with Rupture after it. When fleeing you can best use Rupture at your own feet or just behind it, if an enemy escaped Rupture you can still slow them with Exhaust.

• Flash: it can help you greatly when you run into a group and have to get out quickly. Or whenever you want to chase an enemy and want to close in quick to slow him/her with Rupture.
• Clarity: it will help out greatly in early game when you ran out of mana, what will happen quickly if you spam your skills too much early game
• Ignite: like I mentioned earlier Cho'Gath isn't the quickest champion so when an enemy is about to escape you might want to quickly use Ignite to secure the kill
• Cleanse: if choosing this one I'd choose it in the tank build and replace it with Exhaust. It can be useful to escape from a group of enemies though I don't use it much.
• Surge: alright I know this seems a bit weird, but in fact it's more useful then you'd think on first sight. Because from Surge you get attack speed and AP, using these bonuses in combination with the combo of Rupture Feral Scream and Feast it will be more powerful but mainly I've chosen this 1 because of this: using this skill in combination with Vorpal Spikes you deal more damage because of 2 reasons: 1) you deal more damage with your Vorpal Spikes. 2) you deal more damage because of the higher attack speed. Remember its alternative it has a reason it isn't chosen in the main set, Exhaust just has more potential. If you decide to use it I'd recommend using it in the AP build.
• Smite:Well obviously for in the jungle build. Every jungler needs Smite even if you got an awesome ultimate like Feast.

Carnivore: Whenever Cho'Gath kills a unit, he recovers 34-68 (+2.0 each level) health and 3.5-7.75 9 (+0.25 each level) mana. The values restored increase with Cho'Gath his level.
Carnivore + Shurelya's Battlesong will cause you to regenerate both mana and health quickly. I personally think this is an great passive for a tank like Cho'Gath because you'll need less (or none) lifesteal items and also less mana regeneration/ health regeneration items.

Rupture:Ruptures the ground at target location, popping enemy units into the air, dealing damage and slowing them. Ruptures the ground at target location. After a short delay, enemies are launched into the air for 1 second, dealt 80/135/190/245/305 (+1) magic damage, and have their movement speed slowed by 60% for 3 seconds.Cost: 90 Mana, Range: 950.
Rupture is like the most useful skills of Cho'Gath if you ask me, combining fleeing and chasing possibilities with great damage. It comes to it's best use when combined with Rylai's Crystal Scepter, leaving your enemies barely able to move. Now, I'll come back on the burst combination I mentioned earlier. By using Rupture in combination with Feral Scream and Feast you'll most likely kill squishy enemies like Fiddlesticks (I succeeded at this quite a lot) and leave stronger enemies like Graves crippled to be finished off by allies.
tip:When enemies are running use Rupture in the direction the enemies are heading at a distance that the outer circle is at the feet of the enemy.

feral scream: Cho'Gath unleashes a terrible scream at enemies in a cone, dealing magic damage and Silencing enemies for a few seconds. Cho'Gath screams in a cone in front of him, silencing enemies for 2/2.25/2.5/2.75/3 second(s) and causing 75/125/175/225/275 (+0.7) magic damage. Cost: 70/80/90/100/110 Mana, Range: 300
Feral Scream is extremely useful against mages. But it can be usefull on more ways like when Tryndamere is chasing your ally which has low health you can silence him so he won't use Spinning Slash.

vorpal spikes: Cho'Gath's attacks passively release deadly spikes, dealing damage to all enemy units in front of him. Toggle: Cho'Gath's physical attacks launch spikes that deal 20/35/50/65/80 (+0.3) magic damage to a line in front of him. Cost: No Cost, Range: 40
Vorpal Spikes is useful with farming minions quickly. It will be even a greater help when you bought Rylai's Crystal Scepter, because from that moment when Vorpal Spikes is toggled on even your basic attack slow enemies.
tip: When attacking a tower while enemy champion is near- toggle off else you might hit champion and tower will target you.

feast:Devours an enemy unit, dealing a high amount of damage that ignores magic resist. If the target is killed, Cho'Gath grows, gaining maximum health (maximum 6 stacks). Cho'Gath loses up to 3 stacks upon death. Deals 300/475/650 (+0.7) true damage to target champion, or 1000 true damage to target minion (ignores resists). If the target is killed by Feast, Cho'Gath grows, gaining 90/120/150 maximum health (maximum 6 stacks). Cho'Gath loses up to 3 stacks upon death. Cost: 100 Mana, Range: 100
Feast is a great ultimate for both tanking and dealing damage. It deals true damage what means that it ignores all magic resist, and when you kill an enemy with this ultimate you get extra maximum health! Even though be careful when dieing because you'll lose half of the bonus maximum health you've gained.
tip: If you're having trouble getting enemy champions to low enough health Feast on minions till you reach max bonus (6 stacks)
tip: Many people forget that after you've got the maximum bonus health you can use Feast as an high potential damage skill, you don't need the enemy to die from it anymore!

As people who read my guide before I updated it might have noticed I decided to make skill sequence and skill explanation 2 different chapters this is because the skill sequence was getting too long.

So before heading on with the further I thought this would be a good time to show you some video I made specially for this build it's how Cho'Gath looks like in its most massive form, with Wild Growth, Surge,storm shield and the maximum stacks of Feast
Play Video
Like my video on youtube if you liked it thx ^^

why I've chosen this order: I start up with Rupture because it can hit more then 1 champions at a time and slows them, what can help you with getting you or your ally getting first blood, or saving your ally when both the enemies targeted him. After Rupture I chosen to level I've chosen to level Rupture and Feral Scream equally to get both damage and utility at level 3 1 point in Vorpal Spikes and last this as last Of course I level up Feast whenever possible, I don't think I need to explain this choice.
Why I've chosen this order: This skill sequence seems a bit hard if you look at it in the beginning and it isn't some standard sequence you'd use but it's quite easy when you think about it. If you didn't notice it yet the order is as following: first level up the first 3 skills in order, then max out Vorpal Spikes, I did this because the fact you're a tank what means you'll probably get less kills then the others so you need to get your gold form somewhere else: farming. Then level up Rupture and Feral Scream, keep those 2 about the same level with this your possibilities to escape and/or cripple your enemies by both slowing and silencing them gets maximized much quicker then by leveling them apart. And of course get Feast when you got the chance.
Why I've chosen this order:At first we level Rupture because of it great damage and it slows your enemy what gives you more time to damage your enemy. Then we take Feral Scream to deal damage and leave enemies unable to use abilities what is very useful on champions like sokara because you got more time to kill them while they're not able to heal. As last we take Vorpal Spikes since if you're a bit good with AP Cho'Gath you won't need to farm minions much (though it's always useful with Carnivore). And, here it comes, you wouldn't expect it, yes indeed, we take Feast whenever we can.

Why I've chosen this order:So i've chosen this order because of the fact that in the jungle your Vorpal Spikes in combination with Malady will deal most of the damage because of the quite long cool down on Rupture and Feral Scream. After that I chosen to keep Rupture and Feral Scream around the same level.

• Doran's Ring: +80 Health +15 Ability Power +5 Mana Regen per 5 seconds
  
  item for that early game ability power and a small mana regeneration boost so you can use your skill more often, of course the health bonus is never bad on Cho'Gath. This all together makes a fine starting item.
• Boots of speed:UNIQUE Passive: Enhanced Movement 1 (does not stack with other Boots)
  
  It gives you bit more mobility which gives you more chance on successful escape and chasing
• Tear of the goddess: +350 Mana +7 Mana Regen per 5 seconds UNIQUE Passive: Each time you use an ability, your maximum Mana increases by 4 (3 second cooldown). Bonus caps at +1000 Mana. Does not stack with Archangel's Staff or Manamune
  
  From now on you can spam your abilities a lot more because of the mana regeneration and every time you use a spell you get an extra 4 maximum mana.
• Mercury's treads:+25 Magic Resist UNIQUE Passive: Enhanced Movement 2 (does not stack with other Boots) UNIQUE Passive: +35 Tenacity (Tenacity reduces the duration of stuns, slows, taunts, fears, silences, blinds and immobilizes. Does not stack with other Tenacity items.)
  
  So obviously these are tank shoes, magic resistance and tenacity. Well this quite much reduces the effect of all skills both in damage and in special effects like slow stun etc, don't think I need to explain more.
• chain vest:+45 Armor
  
  So I noticed after playing for a while that early game you just don't have enough armor to survive against AD carries so I’ve decided to put this item here to build up some armor while concentrating on the main items.
• Abyssal scepter:+70 Ability Power +57 Magic Resist UNIQUE Aura: Reduces the Magic Resist of nearby enemy champions by 20
  
  A double effect item at once since you deal more damage and the enemies take more magic damage because of the magic resistance reduction!
• guardian angel:+68 Armor +38 Magic Resist UNIQUE Passive: Revives your champion upon death, restoring 750 Health and 375 Mana (5 minute cooldown).
  
  Great item for tanks, gives more survivability with extra magic resist and armor and once in the 5 minutes revives you! Give everything you have to protect your team you'll have a second chance to escape, got killed in 1 vs 1? Don't worry just get back up and take revenge! And you won't lose any stack when being revived.
• archangel's staff:+400 Mana +25 Mana Regen per 5 seconds +45 Ability Power Passive: Grants Ability Power equal to 3% of your maximum Mana. UNIQUE Passive: Each time you use an ability, your maximum Mana increases by 4 (3 second cooldown). Bonus caps at +1000 Mana. Does not stack with Tear of the Goddess or Manamune
  
  Mana, mana regeneration, ability power AND a passive that gives you extra ability power equal to 3% of your maximum mana. I buy this item this late because I think the other items have more use and this item will only come to it's full potential when it's maximum mana passive is stacked as high as possible, this is why I bought Tear of the Goddess earlier too, when you buy this item the stocked bonus mana in Tear of the Goddess gets transferred to this item.
• warmog's armor:+920 Health +30 Health Regen per 5 seconds Passive: Minion kills permanently grant 3.5 Health and .10 Health Regen per 5 seconds. Champion kills and assists permanently grant 35 Health and 1 Health Regen per 5 seconds. Bonuses cap at +350 Health and +10 Health Regen per 5 seconds.
  
  So this is your source of health en health regeneration in this build, very useful specially with your Vorpal Spikes since you'll farm minions fast you'll be able to stack this item quite quick, where much champions take it early game for the stacks you can fill it up so quick you can easily get this late game
• rabadon's deathcap:+140 Ability Power UNIQUE Passive: Increases Ability Power by 30%
  
  Well extra ability power +another 30% ability power. Your resource for damage, nothing more to be said.

• regrowth pendant:+15 Health Regen per 5 seconds
  
  early game health regen, I've got magic resist armor and health in my runes but no health regen so it's the first thing we take.
• mercury's treads:+25 Magic Resist UNIQUE Passive: Enhanced Movement 2 (does not stack with other Boots) UNIQUE Passive: +35 Tenacity (Tenacity reduces the duration of stuns, slows, taunts, fears, silences, blinds and immobilizes. Does not stack with other Tenacity items.)
  
  So obviously these are tank shoes, magic resistance and tenacity. Well this quite much reduces the effect of all skills both in damage and in special effects like slow stun etc, don't think I need to explain more.
• Glacial Shroud: +425 Mana +45 Armor UNIQUE Passive: +15% Cooldown Reduction
  
  This item you'll most likely get around level 6, so armor to deal with AD DPS-ers a little mana bonus which will help stay in the lane longer. And most useful too 15% cool down reduction, this will greatly help getting the stacks for Feast faster what of course is important for your health boost being a tank and all.
• Force of Nature: +76 Magic Resist +40 Health Regen per 5 seconds +8% Movement Speed UNIQUE Passive: Restores 0.35% of your maximum Health every second.
  
  Well being Cho'Gath with his great health bonus is fun and all, but what use has it when once you lose a quarter of your hp you'll hardly get it back? Of course you can get your health back using Carnivore but Force of Nature will also help a great deal. So easily said: great item for health regeneration. And of course the magic resist helps too.
• Frozen Heart: +99 Armor +500 Mana UNIQUE Passive: +20% Cooldown Reduction UNIQUE Aura: Reduces the Attack Speed of nearby enemies by 20%
  
  Well armor, mana, cool down reduction, I don’t think I’ve to explain those things. The thing that caught my attention too when choosing item is how you help your whole team thanks to its attack speed reduction, this will lower the damage greatly with a team that depends on attack damage.
• Banshee's Veil: +375 Health +375 Mana +50 Magic Resist UNIQUE Passive: Gain a spell shield that blocks the next incoming enemy ability (45 second cooldown).
  
  So first: health, I this gives a small bonus I know I got quite a lack of it in my build but that's because of Feast it gives great health bonus, so I concentrated on making sure you don't loose your health to quickly. Further, obviously great tank item, magic resistance and once in a 90 seconds it blocks a ability completely (fun when the enemy uses his ult exactly when you got this effect). And a small mana bonus always useful for a mage like Cho'Gath because even though you play like a tank don't forget, you're a mage
• guardian angel:+68 Armor +38 Magic Resist UNIQUE Passive: Revives your champion upon death, restoring 750 Health and 375 Mana (5 minute cooldown).
  
  you're a tank not immortal, at least that's what they say. With this you might be able to convince them otherwise. Great item armor magic resistance, and a revive once every 5 minutes. Using this revive you can go all rampage for getting that 1 kill or give everything to save an ally, and the best you won't lose any stacks upon dieing.
• abyssal scepter:+70 Ability Power +57 Magic Resist UNIQUE Aura: Reduces the Magic Resist of nearby enemy champions by 20
  
  As last but not least: Abyssal Mask giving using this to catch up the magic resistance with armor and give you AP, wait AP!? Didn't see that before in this tank build. That's right, at the end I thought lets at least give you a little damage, and a double effect at once since you deal more damage and the enemies take more magic damage because of the magic resistance reduction!

replace mercury's treads by ----> ninja tabi it gives you a greater defense against AD but be carefull if the enemy team got to much crowd control (like silence stun etc etc) keep Mercury's Treads

replace abyssal scepter by ----> zhonya's hourglass this give you more armor and abilities power though it doesn't have the aura to low magic resistance it will give you the option to become invulnerable for 2 seconds, it might not seem long but it saved my *** many times because maybe in these 2 second you team can just get to you and scare the enemy off

replace banshee's veil by ----> thornmail it won't give you mana or HP but it will give you an great defense again AD damagers since it will give you 100armor and it will return 30% of the damage you get to them selves

replace glacial shroud by ----> kindlegem it will give you a small HP boost mid game but I'm more interested in the 10% cool down reduction which will let you stack up Feast faster mid game.

replace frozen heart by ----> spirit visage this will still give you the 10% cool down reduction and it will give you magic resistance with it, even more useful is the 15% extra health regeneration and healing effects (it gives more but we got no use of that) which will boost your Force of Nature health regeneration and supports like Soraka will even heal you more now

• Doran's ring: +80 Health +15 Ability Power +5 Mana Regen per 5 seconds
  
  item for that early game ability power and a small mana regeneration boost so you can use your skill more often, of course the health bonus is never bad on Cho'Gath. This all together makes a fine starting item.
• boots of speed:UNIQUE Passive: Enhanced Movement 1 (does not stack with other Boots)
  
  it gives you bit more mobility which gives you more chance on successful escape and chasing
• tear of the goddess: +350 Mana +7 Mana Regen per 5 seconds UNIQUE Passive: Each time you use an ability, your maximum Mana increases by 4 (3 second cooldown). Bonus caps at +1000 Mana. Does not stack with Archangel's Staff or Manamune
  
  from now on you can spam your abilities a lot more because of the mana regeneration and every time you use a spell you get an extra 4 maximum mana.
• sorcerer's shoes: +20 Magic Penetration UNIQUE Passive: Enhanced Movement 2 (does not stack with other Boots)
  
  this will of course give you more mobility and it empowers your abilities great because of the +20 magic penetration.
• Sheen:+250 Mana +25 Ability Power UNIQUE Passive: After using an ability, your next basic attack deals bonus physical damage equal to your base Attack Damage (2 second cooldown). Does not stack with Trinity Force or Lich Bane.
  
  So Hextech Revolver was here earlier but I noticed it's not as useful as it seemed since the passive Carnivore gives you enough survivability. I had to think of something new and then the Sheen came in, it's a nice item for the mana and ability power boost, but except those two it also strengthens your basic attack since because of Vorpal Spikes your basic attacks still are a great source of damage.
• rylai's crystals scepter:+500 Health +80 Ability Power UNIQUE Passive: Dealing spell damage slows the target's Movement Speed by 35% for 1.5 seconds (15% for multi-target and damage-over-time spells).
  
  I think this item is really necessary not only because of its extra health and ability power, but also because of the fact that with this combined with Vorpal Spikes even your basic attack slow.
• rabadon's deathcap:+140 Ability Power UNIQUE Passive: Increases Ability Power by 30%
  
  well extra ability power plus another 30% ability power. Your resource for damage, nothing more to be said.
• Lich Bane:+350 Mana +80 Ability Power +30 Magic Resist +7% Movement Speed UNIQUE Passive: After using an ability, your next basic attack gains bonus physical damage equal to your Ability Power (2 second cooldown). Does not stack with Sheen or Trinity Force.
  
  Replacement for Will of the Ancients. Upgrade of your sheen futher empowering your damage output and it works just find with Rylai's Crystal Scepter since the movement speed let's you catch up to your slowed enemies even faster
• archangel's staff:+400 Mana +25 Mana Regen per 5 seconds +45 Ability Power Passive: Grants Ability Power equal to 3% of your maximum Mana. UNIQUE Passive: Each time you use an ability, your maximum Mana increases by 4 (3 second cooldown). Bonus caps at +1000 Mana. Does not stack with Tear of the Goddess or Manamune
  
  mana, mana regeneration, ability power AND a passive that gives you extra ability power equal to 3% of your maximum mana. I buy this item this late because i think the other items have more use and this item will only come to it's full potential when it's maximum mana passive is stacked as high as possible, this is why i bought Tear of the Goddess earlier too, when you buy this item the stocked bonus mana in Tear of the Goddess gets transferred to this item.
  
• void staff:+70 Ability Power UNIQUE Passive: +40% Magic Penetration
  
  last but not least void staff, fitting with the terror of the void i think, it gives +70 ability power and plus another 40 magic penetration, now you'll be sure you can destroy any thank that approaches you.

• cloth armor &3x health potion :+18 Armor , Click to Consume: Restores 150 Health over 15 seconds
  
  we'll make a standard jungler start, cloth to defend against the monsters and health potions for when you get below 50% health.
• tear of the goddes :+350 Mana +7 Mana Regen per 5 seconds UNIQUE Passive: Each time you use an ability, your maximum Mana increases by 4 (3 second cooldown). Bonus caps at +1000 Mana. Does not stack with Archangel's Staff or Manamune
  
  to get that extra mana pool that we don't really have as Cho'Gath and since you can get the blue buff you can spam your Rupture and Feral Scream to stack it up quick.
• boots of speed :UNIQUE Passive: Enhanced Movement 1 (does not stack with other Boots)
  
  movement speed. Nothing more to say.
• malady :+25 Ability Power +50% Attack Speed UNIQUE Passive: Your basic attacks deal 20 bonus magic damage and reduce the target's Magic Resist by 6 for 8 seconds (effect stacks up to 4 times).
  
  ability power and attack speed goes great with your Vorpal Spikes especially in jungle.
• Mercury's Treads :+25 Magic Resist UNIQUE Passive: Enhanced Movement 2 (does not stack with other Boots) UNIQUE Passive: +35 Tenacity (Tenacity reduces the duration of stuns, slows, taunts, fears, silences, blinds and immobilizes. Does not stack with other Tenacity items.)
  
  magic resist and tenacity, the tenacity can really save your *** when counter jungled or can give you more success rate in counter jungling
• rylai's crystal scepter :+500 Health +80 Ability Power UNIQUE Passive: Dealing spell damage slows the target's Movement Speed by 35% for 1.5 seconds (15% for multi-target and damage-over-time spells).
  
  to make sure your targets won't escape when ganking or just when trying to flee
• guardian angel :+68 Armor +38 Magic Resist UNIQUE Passive: Revives your champion upon death, restoring 750 Health and 375 Mana (5 minute cooldown).
  
  to give you more survivability and give you that second chance in a team fight or when escaping giving your team maybe just enough time to get to you.
• Archangel's Staff :+400 Mana +25 Mana Regen per 5 seconds +45 Ability Power Passive: Grants Ability Power equal to 3% of your maximum Mana. UNIQUE Passive: Each time you use an ability, your maximum Mana increases by 4 (3 second cooldown). Bonus caps at +1000 Mana. Does not stack with Tear of the Goddess or Manamune
  
  well by now your Tear of the Goddess should be stacked up quite good and will give you quite the ability power boost when grading up into this, also more mana regeneration.
• lich bane :+350 Mana +80 Ability Power +30 Magic Resist +7% Movement Speed UNIQUE Passive: After using an ability, your next basic attack gains bonus physical damage equal to your Ability Power (2 second cooldown). Does not stack with Sheen or Trinity Force
  
  movement speed and ability power plus the fact that it's passive (next basic attack deals bonus damage equal to 100% of ability power) works great with the fact that even though your a mage your also a melee character
