I'm looking at the Prediction of Failure spell from page 232 of Ultimate Magic and I've got just one question: the description says that the spell inflicts both the Shaken and Sickened conditions on someone it affects. Do the penalties from these two conditions stack, or not? I'm assuming they do because it wouldn't make much sense for you to get them both at once, as in game terms Sickened is just Shaken with the addition of an additional -2 to weapon damage rolls along with the -2 to attack rolls, saving throws, skill checks, and ability checks.
Thanks for any help.
they stack
Thanks, Sam_s, that's what I suspected but I wanted to be sure.
