Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Alistar isn't good damage champion, becouse of his colldowns. Whit this build i reduse Alis colldowns and giving him a pushing power.
Use Flash and pulverize to end or begin batle, becouse this skill does greath damage and stun enemies. Headbut can be used to intercept cahneling spell or just help you team mate (or yourself) run away, it also is goo to use whit both flash and ghost . UseTriumrhant roar when ever someone has less health, its greath healing skill. His ulti Unbreakable will is good damage and armor boost. Its good to use this skill when you are destroing turret or when enemies are focusing you, this skill lets you dont get armor or magic resistance.
Sorry for bad english. And about runes, i dont realy know a lot bout them. Runes give you advantage at early game when whith alistar you shoud be careful.
