Well, let's look at the mods:
5% Chance To Cast Level 18 Volcano On Striking
Meh, nothing special...
Level 12 Holy Freeze Aura When Equipped
Neat, but not vital...
+2 To All Skills
Cool, can't complain here. But, other weapons can give better skills than this (Bartucs easily beats it).
+45% Increased Attack Speed
Nice if you use Fade. With Burst of Speed, this mod is wasted.
+330-370% Enhanced Damage (varies)
Makes no difference for a kicker.
-(40-60)% To Enemy Cold Resistance (varies)
The only cold damage you are inflicting is what the Holy Freeze aura adds. At level 12, and with the PvP penalty and resistances, it's not worth mentioning.
20% Deadly Strike
Deadly Strike doesn't tranfer to kicks.
25% Chance of Open Wounds
An UM in any weapon can do this, but it helps.
Prevent Monster Heal
Hmm...Players aren't monsters...
Freezes Target +3
RavenFrost = pwned
Requirements -20%
Meh...
So, all in all, there is 1, maybe 2 good mods on Doom for a kicker. That's the way I see it anyway.
