If you've ever gotten owned by an alistar, chances are they built him somethin like this. Alistar is my favourite champ, and my main. Take flash clairty to maximize your harrassing, tanking, and supporting attributes. Alistar is a vicious champ, kill will be a regular thing if u decide to build him like this. With this build noone can stop you :D.

The extra defense and movement speed is all Alistar needs to run show. Just that one quint of movement makes a huge difference in game, especially with slow Ali. How can u expect to catch ppl if everyone in the game moves faster than u?

Gotta take defensive masteries with Alistar. Tanking is ur main job, taking the extra magic pen will help ur passive as well as ur main damage doing abilities.

It is very important that you take boots of lucidity. Alistars only as good as his moves CD. without CD hes relatively useless in team fights, getting only 1 maybe 2 uses out of his pulverive and headbutt. With this CD reduction you may spam all your moves much faster and effectively to ensure victory. By late game u Can use your heal 3 times in 1 wave of minions, making alistar a heavy support tank. Sheen is also a must, Turning alistar from tank support, to a kill yo' face with my fist special :).

Take Alistars headbutt lvl 1 for the early damgage. at lvl 1 his headbutt does alot, can hit them 3 times usually before lvl 2. Your headbutt does the most damage, but ur ground pound is effective in team fights, max them both together and save ur heal for last. This can be altered depending on your support requirements.

Take Flash clarity, Soloing top or supporting bottom, Alistar devistates his mana. Rather than sacrificeing runes or masteries for extra mana/mana regen, jsut take clarity, to max ur harrasment and under lvling the enemy champs. Late game Clarity is super effective for those long push's, plus, with clairty spamming ur heal is highly useful.

Alistar is the CC king. Utilizing his Area of Effect damage can make or break duels. saving your headbutt is also a very wise maneuver. Alistar is meant to control the enemy players so that the cannot escape. Holding onto that headbutt can help you prevent a flash attempt, or save you for when a gank happens.

I use Alistar all the time, And honestly, i pwn the piss outta ppl using this strategy. Hes good early game, mid game, and late game. Never dying, never running out of mana, supporting, tanking, killing, harrasing, CC the **** outta you champion. Enjoy!
