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.
These are the items i usually use. It is a good thing to have spirit visage to swain, because then his ulti gives him more health each time, and the CD is good to have too. (oh really..) Spell vamp isnt a bad thing either. Spell vamp=more lie steal with spells. At the end i choose the Deathcap and NOT Archangel's staff. The deathcap gives more AP than the Archangel staff will do with this build. I know it gives mana too, but it isnt so important in end game.
