Just curious, death curses were a popular subject a while back, but what about mundane rituals that don't involve anyone dying? How did you power it? What did you do with the power?
My best is about 2,200 shifts of power. I bartered with a summer fae to allow me to stay awake for 11 days without I'll effect to complete the ritual and had a bunch of gator-thropes guarding me. Anyway, I ran for mayor of a city with a fear monger campaign and got 23% of the votes, then inflicted everyone that voted for me with a mild social consequence (implied consent from that group of voters). ... The white council is less than thrilled with my antics.
I talked the GM into a new artifact that grants intelectus over the island the city is on (costs mental stress to use), and cloak of shadows.
How about you guys?
