Creasy's right -- you can always get more defense levels, but you can't go backwards. Try a 1-def, and if it's boring, then make a 30-def turmoil pure. When that gets boring, make it into a rune pure.
As for tips themselves for being a zerker, do you mean training or PKing? The PKing strategy is basically just briding with use of vengenance and Soul Split if you have it.
Superheat is a fairly quick trainin method plus you get amithing levels![]()
