ToME WikiHumans are "boring". Use them if you want a balanced character or a greater challenge.
Humans do possess a couple qualities that many overlook; they have no experience penalty, so they will gain levels quite quickly, and they have a decent amount of hit points, which make them a fine choice for mages, as they get good hit points without the intelligence hit many 'tough' races get, and their fast levelling partially offsets the mages' experience penalty.
