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.
Sion shines through early-mid game and late game Farm well and play agressive if you have a second stun. buy some wards if they have a jungler and harass with your stun and shield combo. Make sure you last hit with youe E spell so you get 1 permenant HP! Dont be a noob and learn when to go B when your dieing. Gl 2 good combos with ap sion is Garren and Sion and Alistar and Sion Also DeathFire Grasp is an Acitive item Make sure to use it. also once your level 6 take the blue buff at all time so you can spam your spells dont be affraid to use your ulti. Have Fun and Rate Me a Good Score cause you know you love this build :D
