grauenwolf said:The Dex DM is part of the attack roll and thus part of the effect. So unless you subtract it back out, you'll be adding both Dex DM and Str DM to the damage roll.
In the same vein, the DEX DM is part of the attack roll for ranged and thus part of the effect. So your DEX stacks with the kinetic energy of a bullet. Makes no sense really other than as a game mechanic.
