What is the duration on a monsters Change Shape Ability. Im looking at the Quasit, but it seems that many monsters have this ability as an SQ.
Change Shape (Su):
A creature with this special quality has the ability to assume the appearance of a specific creature or type of creature (usually a humanoid), but retains most of its own physical qualities. A creature cannot change shape to a form more than one size category smaller or larger than its original form. This ability functions as a polymorph spell, the type of which is listed in the creature’s description, but the creature does not adjust its ability scores (although it gains any other abilities of the creature it mimics). Unless otherwise stated, it can remain in an alternate form indefinitely. Some creatures, such as lycanthropes, can transform into unique forms with special modifiers and abilities. These creatures do adjust their ability scores, as noted in their descriptions.
The spell Polymorph has a duration of 1 min/level, so would you just use the duration of the polymorph spell?
No, you do not use the duration unless stated in the creature's description.
Unless otherwise stated, it can remain in an alternate form indefinitely.
Thanks!
That information was in the quote you provided so the answer was easy. :)
