Hi, I am playing on SEA server ,currently Diamond 5. Ap Alistar top is quite op on this patch so I decided to make a guide of it.

• Greater Quintessence of Ability Power: Major damage of Alistar
• Greater Mark of Hybrid Penetration: Allow you to Shove your Colossal bull c*ck down your enemies throat.
• Seal of Armor: The flat Armor Seals provide early game resistance against AD top laners, the benefit is far greater than scaling for early game survivability alone.
• Glyph of Magic Resist: To provide resistance in case you go against an AP top laner such as Ryze or mid comes to gank.
  

If gonna roam in the early game then I would get these boots. The cooldown helps many to roam and more combo will be done. Ionian Boots of Lucidity also is the cheapest boot in League of Legend.

This item is a MUST for ap champion. It gives you lots of gold from the start of the game . Active it and slow enemy down, it is very good for Alistar because it helps a lot on chasing enemy.

Damage, damage and damage.

Plenty of damage and sustain and no more.

Give damage and armor. Good for engage teamfights and become a golden bull.

Break enemy defensive line and f**k it .

Pros

+Good roaming + Strong late game (AoE cc on short cooldown) + One of the best peelers + Good Towerdiver

Alistar current patch is good with ap at top lane. Just go full ap, rekt enemy backline and Unbreakable Will will be your tank item !!!!

Cons

-W + Q Combos are a vital part of playing him and can be messed up easily which leaves you high and dry. -High skillcap. -Doesn’t have a burst lvl 6.

Alistar need lots of practises to be good at. The game will be messed up or even defeated by a single mistake of Alistar. So we need to play it right.

Make sure to be safe until 6 with the occasional combo thrown at her, then you should have no problems. Riven has a lot of base damage to throw at you early game, keep in mind that her passive allows her to do extra attack damage to you after every ability she casts. Rivens usually follow a similar combo to: Valor in > AA > Broken Wings > AA > Broken Wings > AA > Broken Wings > AA then Ki Burst to disengage, after all of these are cast don't be afraid to harass a bit. however the cooldown is relatively short for the entire combo so beware.

This can be a tricky match up especially as the game progresses, you may need to rely more heavily on the jungler to help get kills. Ryze will try to harass and poke you, and will most likely succeed, he can effectively squander your combo by casting whenever you are getting close to him. If possible attempt to harass him before he can buy a because he spends a lot of his mana early levels to farm and poke you.

Teemo is god , Teemo is satan , Teemo > everyone in league.

A trick I've learned to make doing the W-Q combo very easy:

Make sure your Q or entire skills are on quickcast/smartcast. Cast your W on an enemy. While you are mid-air, PRESS, HOLD DOWN, and DON'T LET GO of your Q button. The Q will instantly cast after the W channel.

I've done this over and over and it works no matter how far you are from your enemy when you use your headbutt.

Just imagine you are doing the Yasuo E-Q knock-up combo


Another trick:

When you want to do the Flash-Q-W combo , DON'T FLASH FIRST , press Q then instant Flash and W back enemy. This way is more faster and better.
