"Wait again, that didn't work right" - the Dysfunctional Rules Collection

[The Random NPC]

Well not a whole lot of gold, xp is a river, and he has 14 hours and 45 minute free time available every day anyway. Basically Wizards get to break the law of thermodynamics at level 5, and even get a free feat slot to power it.
