GM Frost's A Level 1-5 Adventure of PFS (2E) Escapades

Game Master Frozen Frost

I don't have the full grasp of Incapacitation trait, so I might need some help here. Keff's Dizzying Colors is just Rank 1, so Level 3 and above target has their result one degree better, right? So if Otani fails the saving throw, it becomes Success?

Yes, exactly. Unless Keff heightened it.

Think of it as a Higher-Level creature's Laugh as the Lower-Level creature tries to knock him out with one hit using a very wimpy spell. "Ha ha, you fool. You think some silly rainbow is going to distract Me!?"

As a caster, if you want your Incapacitation spells to "work", you must prepare them in your highest level slots.
