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.
This is....The most indestructible Swain build I've ever created.
Indestructible. (Once this build finished, I have never died.)
Outlast any opponent.
Clarity is necessary. :( Don't get too much mana until your first Rod of Ages, so ya don't last long in extended combat.
Without ignite, you don't deal enough damage to nuke someone before they realize they can't kill you and run away.
Have fun leading the push :D
