Adept: 100% damage dealt on you, 100% damage dealt on NPC
Expert: 150% damage dealt on you, 75%~80% damage dealt on NPC
Master: 200% damage dealt on you, 60%~66% damage dealt on NPC
Apparently, the NPC damage reduction applies on all NPC, including your summonings/followers. Which means on higher difficulties, your summonings and followers are MUCH more tougher than on adept or lower.
If you're a mage, there's no point to play at Expert or Master at higher levels, because your spells' damage is static, and enemies are getting tougher. What's the point of gimping yourself an additional 40% damage penalty?
