Do priests get a benefit to their supplications based on wisdom? Its their prime stat but aside from practices and slightly better mana gains there doesn't seem to be a whole lot of reason to max out wisdom if there's no practices/level difference. Example would be humans, is there a good reason to keep wisdom at 23 instead of at 20?

Just curious, I know they play a part with paladins but wanted to know in regards to other communers like shamans, druids and healers.
