Alright... So I've recently been working on a character with 15 precrowns. Slightly ludicrous, but the point is to go into the ID and dragon gold double, then level around ID40 looking for greater moloch threat room. I had a wizard that accomplished this, with 50 effectiveness magic missile and 6000 casts. Has 2 AoLS and a couple boar skulls, SoCR and PoCR aplenty. The character surfaces, alternately sacrifices ~20 mil and kills a beggar to get to N-, then prays for a precrown. More money is needed at precrown 13. I sacrifice 75 million, and all of a sudden I'm C-, and Holy Slayers are summoned.
I'm still thinking "Wait what?" so I go to pick up a random precrown to bash slayers with. And then I'm sacrificed. Boom. I'm incredibly stupid.
I figure I piety overflowed the other direction, so the N god hated me and summoned. However, the alter was neutral as I converted after sacing so it wasn't converted as well. I guess piety overflow works in the opposite direction as well... Damn.

Of note: My stuff is all on the ground, but you can see the awesome skillset and magic marks. Magic missile owned everything. And the kill list. Check ancient karmic dragon and greater moloch. I killed a lot of them.
