Changes

Killing [[monster]]s of about the same [[level]] as your [[character]] will gain your character more experience, while monsters are worth a decreasing percentage of their full value as they get further above or below your character's level. It's likely that experience will be gained from [[quest]]s as well, similar to how it works in [[World of WarCraft]].

Play testers from the [[BlizzCon 2008]] demo build (October) reported that the level up speed, from 5-10, was about the same as it is in [[Diablo II]], or perhaps even a bit faster. How well the progress rate in that demo of the game will correspond to the final game is not known.
