I'm toying with adding an extra guise of Aroden as a Circus Performer. ExCurse is the circus AP and I'll be damned if I don't play that up at every chance I get.
I'm a bit of a Golarion noob, so idk what exactly that might impact in the lore, but it seems an easy enough change to the AP. Obviously that calls for an extra statue and mask in Moonstone Hall, then an extra trial later on.
For the Trial, I'm thinking of incorporating a Performance Duel as introduced in book 1. The opponents might be guardians placed by Aroden, a troupe of Xulgaths who bested the trial earlier, or most interesting imo, a handful of Celestial Menagerie performers. We know Dusklight was handing people over to the Xulgaths as sacrifices, it's not outside the realm of possibility that Sarvel took some for precisely this trial.
There's probably more little things I'm missing, but my final change for now is to make Clownish Curse a divine spell for followers of Aroden. Praise the god of humanity and clowns!
