I have a question about ebb and flow for the mystic class feat.
The Feat say, "With careful focus, you guarantee that vital energy lost from a target is caught by your vitality network. If the next action you use is to Cast a Spell that deals void damage to a single target and the target loses Hit Points from the spell, your vitality network gains Hit Points equal to twice the spell’s rank. If your next action is to Strike with a weapon that deals void damage, your vitality network gains 2 Hit Points per weapon damage die."
Lets say the laser rifle does 3d10 fire damage because of greater striking, and an entropic destabilizer that does 1d4 void damage.
Is that weapons base damage the weapons damage dice used since the weapon does do void damage with the attached module?
