Bestow Curse says:
You place a curse on the subject. Choose one of the following.
–6 decrease to an ability score (minimum 1).
–4 penalty on attack rolls, saves, ability checks, and skill checks.
Each turn, the target has a 50% chance to act normally; otherwise, it takes no action.
You may also invent your own curse, but it should be no more powerful than those described above.
The part I am interested in is the invent your own curse part of the spell. Has anyone used this part during a scenario and what have you chosen?
I am trying to figure out what is possible? I know that there may be table variability with GM's. Do people think it would be good for my character to have a list of choices and then have the GM peruse them before the game?
Thanks
