[Suzerain of Sheol]

Same! That was easily my favorite quest in the game. Plus, it was just so fun manipulating all the guests.

On the other hand, the last legitimate assassination (I think it was) where you have to kill the guy who prays at the statue of the Night Mother... that was an embarrassing one for me.

I got in position early that day, had like 60% chameleon on and was hiding on the roof with my bow, waiting for him. And... somehow, he senses me, shoots me with a paralysis arrow before I even know what's happening, and I tumble off the roof and die of shame.
