Do damage reduction debuffs stack? I noticed that multiple classes have the ability to debuff enemy damage by 20-25%. Anyone know if these effects stack? If they do stack, I'm sure it will be multiplicative and perhaps capped. (WD) Bad Medicine- 20% damage reduction when damaging enemies with poison. (Barb) Threatening Shout- 20% damage reduction for 15 seconds. (Monk) Resolve- 25% damage reduction when damaging enemies. (DH) Numbing Traps- 25% damage reduction when damaging enemies with certain skills. If all these were stacked, you would get enemies doing 36% of normal damage. Even if there is a cap, it seems like these skills will be extremely important in Inferno difficulty.
