prevent monster heal is the problem (uber regens alot)
suggestion
1 skill into poison creeper - while poisoned dclone will not regen health
alternatively hit it once with a prevent monster heal item equipped (need to land attack)
(a 30/-30 sword would also do alot for dps, but the main issue is definitely regen)
unless u have a conviction merc
assuming perfect -25 ravenlore against 95 fire res clone , then he's 70 res
means ur dmg is multiplied by a factor of 0.3
a -30 sword puts him at 40 res, and dmg multiplied by a factor of 0.6
it's going to be more than double dps, because of the +30% fire skill damage on the sword.
Oh wow that is a huge increase. Ill work on getting one of those. Great idea with poison creeper, that will definitely help.
