Retribution (Su)
Effect: A witch can place a retribution hex on a creature within 60 feet, causing terrible wounds to open across the target’s flesh whenever it deals damage to another creature in melee. Immediately after the hexed creature deals damage in melee, it takes half that damage (round down). This damage bypasses any resistances, immunities, or damage reduction the creature possesses. This effect lasts for a number of rounds equal to the witch’s Intelligence modifier. A Will save negates this effect.
If the attacked creature has DR, does the attacker take half damage before or after taking into account the damage reduced?
After Damage Reduction. Damage reduced by DR hasn't been dealt.
I am on the other side of the fence with this. I deal damage, but not all gets through. DR, Hardness, and Energy Resistance can reduce the amount that gets through. Vampiric Touch has a similar issue, and I think it was ruled to get current hp + con as the max.
Wish I had some rules to show which way this goes.
