Threats to Zilean with this build
|Ashe||Weak poke, her slow is useless agains your speed-buff. She cant evade your stun without flash.|
|Shen||His low-range taunt is dangerous, but if you evade it correct he is easy fed for you. Just poke and bomb him down.|
zilean has a huge amount of neverending stuns. If your team is not to dump they will have a lot of time to kill enemys in teamfights. On top you can revive one teammember ... thats usefull too.
Your primary job is stunning!
your 2nd job is reviving the game carry of your team.
Dealing dmg is just a nice side effect - but with this build you have nice dmg vs squishy champs.
You need skill to land your stun. And you need skill to use your ulti in the right moment on the right champs ... and you need skill to place your slow/speed on the fitting ally or enemy. It needs time to learn all this - but if you learned it you have a AOE-stun that stuns enemys 60% of the fighttime.
To be usefull in teamfights and stun the enemys a lot you need to be not to squishy. So we stack Health! We add armor and magic-resist into the rune page, so we dont need to buy armor-items. But there are great items that have HP and Ability Power combined! With all the HP you will be quite tanky, assasins wont be able to burst you. In teamfights killing you will need the enemy time ... time your team can use to kill them. And while they kill you you can stun them ... again ... and again ... and again! And then you die ... and place the revive on you. In most times the fight is allready won the moment you revive :)
If the enemys dont focus you in the fight you will still stun them. Again ... and again ... and again. And you will revive your carry. You will be super annoying.
But you need to be tanky to do so. If you are down in 1 second you are useless :(
Greater Mark of Armor
Greater Seal of Scaling Health
Greater Glyph of Scaling Magic Resist
Greater Quintessence of Scaling Cooldown Reduction
Greater Quintessence of Gold
For runes you take Armor, Scaling Magic Resist, Scaling Health and 2 Scaling CD-Reduction Quints + 1 Gold/s Quint. You can also put Flat runes, but scaling Runes allready pay out after Lvl 6, so after 5-10 minutes game time. You dont need to put the Gold-rune, but some extra gold is nice to have.
Why you need so much defence?
Well, you are squishy ... and you wont build any Armor or MR item. There are many Assasins around, just made to kill you. Your stun and your revive are useless if you are bursted down in milliseconds. Also putting some AP in the runes (maybe around 20 AP with full AP-runes) is not realy helpfull ... as soons as you have your first items 20 AP is like nothing. The armor, HP and MR will support you the hole game, making your Health given from the Items a lot more worthy.
With this runes nothing will burst you, so you have time to put stuns and revives. Even if its just a second auto-attack the assasin need to take you down - thats time enough to stun him and put revive on you. If they towerdive you will stun them and revive - while they take huge dmg from the tower. The same in teamfights - you tank the ultimates and revive - your team has time to kill them.
Supporter Masteries = Cunning Tree. Everything should be clear, expect "Runic Affinity". Well, all stuff from the Cunning Tree is super usefull, expect the 2nd Step. You have a refillable Pot, so you dont need Cookies (Secret Stash). What is left is 2% more Dmg when you fight alone or more time with the blue buff. You are not an assasin, so you better dont fight alone. But from time to time your bombs might kill someone with a blue buff or red buff on it.
Both buffs are very strong on you - its nice to hold them a little bit longer.
Ok, if Ferocity-Tree (Damage) or Resolve-Tree (Tank) is up to you. The dmg Tree will grant you about 5% more dmg and some extra dmg for Allys after you hit an enemy.
The Tank-Tree will give you some HP and substain for early game. Remember you dont have any heal-ability, its great to have some help surviving early in lane. Also -15% CD for your Flash and Exhaust is very mighty. I prefer this Tree.
You can just read the notes i made in the item-part :3
In general its easy.
1) supporters want an gold items and place many wards
2) you need 30% cooldown reduction to stun a lot (+10% you get from the runes)
3) You need some mana (zilean is addicted to mana)
4) You want HP to get tanky
5) Ability power are great too!
Zilean has no heal nor lifesteal. Allmost any champ on bottom-lane has some poke ability ... you need something to refill your health. Not just 2 cookies for the first 5 minutes. You wont be able to heal the hole laning phase. You will waste a lot of cash or time if you buy cookies or homecall each time you take damage. This pot solves all your problems. Trade on your lane and feel good when you see the enemys wasting gold for cookies, while you just refill your potion again and again for free :3
Frost Queen's Claim
Each supporter needs a gold item! This one is made for you. Its important that you try to use the gold-on-hit-effect. Bomb+Autohit and allready a few gold earned. Sure dont risk to much - find the right moment to poke enemys. The enemy adc must lasthit minions - thats a good change to give him a hit. Or the enemy support is meele - if he hits a minion you can hit him back and put bombs on him.
It also has Cooldown-reduction (very important!) and AP (nice to have).
And on top the active (Icy ghost) can slow the enemys - making it easy to double-bomb him. If you run away you can use the active to slow your chaser. And if you chase you can slow your victim. But its not just for fights - if you wanne ward an unsave area you can check first with the Icy ghosts if noone is hiding in the bushes.
Vision is very important! Without vision the best carry will fail - being ganged or traped. So many kills can be avoided by seeing the enemy coming. And even better - if you see them coming you can start counter-ganging.
There is no need to hold the wards to long in your inventory - they will refill each time you go back to the shop - so put them as soon as you reach unwarded area.
Also the sightstone has a great Health Buff. You need health, you dont wanne be squishy.
The Ruby Sightstone and Fronst Queen are both awesome items giving you a lot of stats you need.
They are worth blocking 2 itemslots! Dont combine them to one item, you will lose a lot of HP, a strong active skill and some AP. Each time you get killed when moving into unwarded area or each time the enemy is running away with 10 HP you will damn yourself for not having the Icy-Ghost Active and Ruby Sightstone.
Boots of Speed
Your speed-skill is great, but not perfect. You need a little bit extra speed from this boots. For many enemys its ok to keep the boots without an upgrade until lategame (when you sell them for Ludens Echo). If the enemy is strong you can still upgrade them. Thanks to your rune-pages you dont need the Cooldown-reduction boots. So you can build Anti-magic boots if you get into a lot of stuns. Or get Swiftness boots if you have problems with roaming. If you have extra cash you can also get the magic-penetration boots.
This item is awesome on Zilean! It has all you need and is the reason why this build is way stronger compared to full-tank zilean (with frozen hearth and command banner). This pink book gives you 20% cooldown reduction. Also the extra mana and mana-refill-passiv will solve your mana-problems. On top you get a lot of AP. Befor you get this item your mana-management is realy difficult ... and as soon as you have it you are able to hit a few skill-combos and still be able to cast your ultimate.
Rylai's Crystal Scepter
There are many AP-items around. The point on this 2 items is they grant you a big Health bonus! As soon as you have them together with the Ruby stone your life-bar will look like the one from Shen or Darius (> 3000 HP). You get cooldown reduction and Mana from your other items, there is just nothing more you need then AP and HP - and these 2 items will give it to you.
If your build is complete and you have a lot of gold you can sell your boots and get this item instead. The 10% movement boost is equal to upgraded boots. The AP and passive effect is nice to have - in most cases its more usefull then the effects on upgraded boots.
Buy one of these at Lvl 9. Take what you need more. If your team is lazy on putting wards, you might want the permanent wards. If the enemy team is putting million wards and noone of your team has ward-detection you take the Oracle Alteration.
Your ultimate. Sure you skill this one on Lvl 6, 11 and 16.
Max this one first. If you wanne kite you need damage. If the enemy goes all in you must deal dmg to kill them first. Also the cooldown reduces per level, so you can stun more frequently.
2nd skill you max up to Skill-Lvl 4. On Lvl 4 rewind has allmost the same cooldown than the bomb, so you can double bomb all the time. Level 5 has allmost no more benefite, so skill it on Lvl 17.
Max this one last. The speed boost is nice, but less important compared to your double-bombs.
Use your ulti as late as possible. If you put it to early the enemy will just wait a few seconds and kill your teammate as soon as the effect ends.
Most effective on assasins or the adc - a tank will revive with low health and most likely go down again.
This spell is not only for your adc because you are his supporter. Its made for the teammember that carrys the game. If your adc is noob and just feeding use it on mid or the jungler - or even yourself.
Here it is, your overmighty AOE-low-cooldown-stunning skill. Easy to use, but hard to master. 2 bombs on the same target and it is stuned. it needs a lot of time to learn how to place the bombs, to expect the enemy movements correct or just to hit the keys fast enough.
Keep in mind: It is easy to stun slow targets. Minions next to a champ can be bombed to stun him (AOE-stun). Tanks can be stuned, because most of them dont have evade-skills. Exhausted enemys can be stunned easy. You can use your slow-spell and bomb them afterwards, also easy made stuns.
You are the time mage. You decide who moves how fast. You can slow a lot ... or speed and run away very fast. you can block ways with double-bombs making it impossible for enemys to chase you.
But its importent you keep in mind what skills the enemys have. Do they have flash ready? Then they can evade your stun 1 time. Do they have evade-skills like ezreal or Vayne? Then they can evade again your stun. So in teamfights attack a target that cant evade, is out of flash or just has a slow reaction time. You can use the double bomb to force the enemy to set his evade skills on cd. Or you can wait until he wastes it and bomb him afterwards.
This will just reduce the cooldowns of your Q and E. On Skill-Lvl 4 the cooldown will be similar to the bomb-cooldown, so you can double-bomb all the time. Befor Skill-Lvl 4 the bombs-cooldown will reset faster then the rewind cooldown. So if you wanne double bomb (in teamfights and gangs you wanne allways double-bomb) you need to wait with throwing bombs until rewind resets too.
Use it to slow enemys, making it easy to stun them. Use it to put wards all over the map with high speed or to rotate the lanes. Use it to run away if you are ganged or to catch up to enemys in case you wanne gang them.
Thx for reading.
Zilean is a great hero to learn aiming skills and he forces you to keep the overview in teamfights. If you take the time to learn him in a few hundred games, you will be of awesome use for your team.
