Here's a cute little runearm for vol to drop. The visual could be a skeletal head with the 'mouth' being the 'cannon'.
Vol's skull (Minimum level 28)
Blast type: negative blast maximum tier 5
Infusion: negative damage VI
Nullification lore X
Life stealing: this runearm infuses your weapons with life-stealing: on critical hits there's a chance to drain 1-3 levels from your target.
Taint of evil
Raid item so more powerful than quest items. Life stealing because enervation might be too good? Plus it's negative so it would be of absolute no use to the actual raid itself or the deathwyrm raid, for the (tro)lols.
