In thinking about it, I was wondering if these two would stack like flaming and flaming burst, or burst and blast etc etc...
Using the Disruption Rune Arm, and a Green Steel Greater Disruption weapon .... would that mean, 4d6 + 6d6 + 200 (on vorpals)? that would completely dominate undead... I'm very excited about this possibility
I thought it wouldn't hurt to ask since they are separate effects!
