Everything has a role, and these ones are tanks, Otherworldly tanks, ones who don't have a normal place among civilization, but have made their own.
In this you will find 3 characters with backstories full of fluff and build guides to help you create them at any level from 1 to 20 as a character or NPC in your game.
