I created this guide beacuse I often see horrible Sion players which didn't know anything about this champion. Remember that sion can be created in 2 ways. As off-tank or mage. In my guide I'll show first way.

Pros:
-good stun
-lot of bonus hp in late game
-good livesteal, attack speed and DMG boost from skills
-his ult heals teamates
-strong on lane with malee DPS

Cons:
-weak early game
-high mana cost of spells
-vulnerable to cc
-quite slow

Top choices


Exhaust is my favourite spell. You reduce enemy movement speed attack demage and ability power. This is skill is usefull in all cases.

The biggest advantage of flash is using this spell over the walls. You can also use it to come closer and start healing or to have better possition to use your Cryptic Gaze.

Other options


Teleport is good summoner spell particularly when you're on solo lane. In early game all huge fights will be on bot lane(near dragon). Way from top to bot is so long so in many cases you will save you're allies.

Ignite is good spell to finish off with enemies or reduce their health regeneration. Personally I don't like this spell, but many people do.

Ghost is good substicute of flash. It also help help you escape or catch enemy. I think that this spell is as good as flash.

Heal is good spell for teamfights. You can also use it in fights to surprise enemy and survive from his attack.

Cleanse is good spell too. It removes all disables from you and lowers duration of next in few seconds. As in case of ignite I don't take this spell to often, but I don't think that it's useless.

In this chapter I will describe three ways to start game with Sion.

Option 1-when you want to stay long on your lane


Option 2-when you go for lane with ranged DPS


Option 3-when your team don't have good tank

Sion is a good champion ,but items are also really important. My items sequence give a little of survivablity in early game ,but your bonus hp from enrage will help you survive. With my build killing you inlate game will be almost imposible. Feel free if you want to change some items.



Very good item if you want to stay on lane for a long time. When you use basic attacks you lose hp, but vampiric scepter will eliminate this effect.


Boots with normal movement speed(2), but with good attack speed boost. You should take them if your opponents dont't have too much CC


Good items for all DPS champions. Sion will have so much more attack speed and critical chance, but the most important thing for him is movement speed.


Increadibly high attack dmg, critical chance and increased crits. It's the best item to buy after phantom dancer.


Now you have huge critical chance so it's time to get some pure DMG. When you stack it 40 times you'll get 100 AD and 25% livestel. You have your ult, but you can't use it all the time.


If you have good DMG so you should become more tanky. Warmog's Armor give you 1.3k hp(the biggest bonus in game). With you're passive from enrage you will have above 4k health.


Very good item to buy after Warmog's Armor. Atma's Impaler will give you about 80 bonus AD, 45armor and 18% critical chance. All this bonuses are really important for Sion so it's one of the best ways to finish you're build.

Not everything goes according to plan so you must have situational items. For example when veigar is feeded you shold buy magic resistance. In this chapter I will show some possible options for every situation.


One of my favourite items. You should buy this item when enemies have hight AD. This lantern gave you free ward every 3 minutes(you can save about 750 gold in normal game). Armor, livesteal and attack also works well. Unique passive give you 20% to deal bonus 425 dmg for minions so it's realy important to kill dragon or baron more quickly.


Very good item when enemy team have strong mages or good CC. All CC are reduced by 35% so it can save you for example from veigars combo.


Good item for people which don't like Phantom Dancer. It's very universal item. It gives you a bit of every thing(HP,MANA,AD,AP,Critical and Movement). Trinity Force also gives 25% chances to slow enemy by 35% for 2.5 second. Despite the fact that slow is really important the best thing in this item is that when you use skill you're next basic attack will deal bonus DMG(+150% of your AD).


Good item when enemy mages are feeded. Bonus 76 magic resistance(biggest bonus in game) will help you survive. Increased movement speed and health regeneration 110hp/5sec is really usefull too.


You should buy this item when enemy have good and feeded nuker(for example Anivia) Banshee's veil gives 50magic resist,375 hp and mana, but the most important thing is that it block negative spell every 45 seconds. Personally I prefer Force of Nature, but this item is good too.

Remember about farming and last hitting. It is relly important for all champions, but for Sion it's esencial. For example when he kill 300 minions he have bonus 900hp from enrage!!! When you dominate your lane you shouldn't push too much. Otherwise you're enemy will get more gold.

Role of Sion in teamfights is obvious. Your team tank(Ammumu,Rammus or another) initiates fight and then you should immediately start fighting. Sion massive heal from his ultimate is really important so your team should win at this time. Many people are asking why I don't initiate fights. First of all if all team will focus on me I will be ignited and then I'll die so I won't heal his teamates.

Sion have 4 good spells.


First of them is Cryptic Gaze. Without this skill Sion would be nothing. Cryptic Gaze stuns a enemy from a quite long range so it helps you catch enemies. Stun is very usefull so we max it second.


Second is Death's Caress. It's the weakest of Sion spells, but it is still usefull. Shield defence at low levels is quite low so you should max it at last.


Third is enrage. It gives you a lot of AD and passive of this skill will let you get bonus hp. This skill makes Sion very good off-tank. This skill should be maxed first.


Last Sion skill is Cannibalism. It's one of the best ultimates in game. You get 100% livesteal and heal allies for half of this duration. It also gives you increased attack speed by 50%. This skill will let you win fight 1 vs 2 and even 1 vs 3 in late game.
