If I have an effect (effect#2) that depends on the existence of another effect (effect#1) and effect #1 ends, does that mean that effect#2, even though its duration isn't up, ends as a result of the created paradox?
Example: I Fiendform into an Erinyes. Fiendform is good for 1minute/level. At level 13, it;s good for 13 minutes. Let's call that effect#1 (Fiendform). While an Erinyes, I cast Polymorph Self and change into a Hippogriff with the intent of flying my buddies over a mountain range. Let's call that Poly Self effect#2. Poly Self is a Spell-like ability of the Erinyes as cast by an 8th level sorc, which means the effect lasts 8 hours. What happens 13 minutes into the Fiendform spell? Obviously I'm not an Erinyes anymore since Fiendform ended. Does my Poly Self effect abruptly end with 7 hrs 47 minutes remaining per the book?
