Do you gain more experience on higher difficulty levels?
I know that it takes more damage to kill enemies, but apart from that is there any more experience gained on the higher difficulty levels?
Solution 1:
Well, yes, and no.
On it's own, altering the difficulty does not affect skill gain rates.
What it does affect is damage done and received, which adjusts the rate it takes to learn offensive and defensive skills.
If an enemy has 300 health on normal and 300 health on master, though it might take longer to defeat him on master, you'll earn the same amount of experience for inflicting 300 damage at the end of the fight.
