Sacred Haven of Debauchery

That's the same Darwin Award laureate I mentioned in the thread about politics. Never anger a level 15 archdevil if you're not a red dragon or the final boss of a campaign.
And that's not the limit; I plan to keep leveling up until I get bored, although with such a powerful hero, the game turns into stomping on weaklings. Oh well, if it gets too boring, I can always burn down the enemy capital.
