So I'm making a Time Oracle for an upcoming game. The Revelation I want is called Temporal Celerity. My Oracle's Curse is Powerless Prophesy. The two effects are diametrically opposed. How do I reconcile them? There is nothing saying I can't take both that I can find.
I think you wouldn't be able to use Temporal Celerity's ability to act in the enemy surprise round. Powerless Prophesy seems like a pretty bad curse for a Time Oracle. Being able to Haste the party (Speed or Slow Time) in the enemy surprise round is a big thing to give up, IMHO.
The Oracle curse. It's a flat bar on acting in surprise rounds ever, Temporal Celerity gives a benefit (always acting in surprise rounds) assuming you already have a normal ability to act in surprise rounds.
