Since damage numbers mean nothing, I'd just stop rolling damage altogether and either make up numbers (I hit him for 173 points of damage), or else start giving percentages of hit points lost (I hit him for 1/4th of his hp.) Since the "dice" are no longer the "fun" part of combat, I'd amuse myself by finding all different ways of describing how much damage I do.
- I hit him for 2 pints of blood loss.
- I hit him and cut his left arm off at the elbow.
- I hit him sixteen times in the stomach.
- I hit him so hard he has to make a death save.
- I hit him for as much damage as a piano dropping on your foot.
- I hit him for 16 hit points for every wound he's thus far suffered in combat.
- I hit him and kill him.
- I hit him and he releases his bowels.
- I hit him for 12 wounds.
Do all this stuff and just see what the DM says or does. Heck, if it was me, I wouldn't even roll to hit... I'd just say I did every time and let him worry about it.
