This should have been either modified to or a fabled version should have been added. Due to the delay and the plain fact the casters suck at melee anyways this thing is worthless.
Here is what I think this item "SHOULD" look like:
MAGIC ITEM LORE ITEM NO TRADE
Slot: PRIMARY
Skill: 2H Blunt Atk Delay: 30
DMG: 15 Dmg Bonus: 81
DEX: +5 CHA: +10 INT: +25 HP: +125 MANA: +125

Now before you all flame me yes this is not what the item really is. Yes the delay and damage is a better ratio and if you think this will make casters have too good of an item you are way off. The INT, HP, and MANA are high simply because this takes up your primary and secondary since it's a two hander. No one will bother equipping an item like this without at least decent stats. Also technically getting the keys and moving all the way up to her (by yourself and let us assume at a lower level)... if you kill her you deserve a decent reward like this. -Peace.
