A Balron Slaying Machine (says so right on the label, Balron Damnation). With DI Maxed, EoO, and Consecrate Weapon, and Discord, this thing will take out a Balron in 4-5 hits (in the video takes a few more because my consecrate was fizzling while I got the video set up)! It does well over 300 damage when combined with Crushing Blow! It's level 100 with 23 spending points left because I like round numbers. Check it out in action.

It's got enough leech to keep stam and mana fully stocked, hit lightning and fireball at 50, 8 str to max damage, SDI to max the hit effects, HLD, and and area to deal with those pesky side mobs.
300 EDs OBO. PM me!
