Polymorph and spellcasting

[Starshade]

Lets say some spellcaster, as a Druid or Wizard gets polymorphed into a creature who usually is able to cast or learn to cast, complex spells, as a Yuan-Ti, Naga or some Demon/Devil. Would a spellcaster still be able to cast spells? and would the Druid keep the wildshape ability?

Class abilities are normally not affected by polymorph... just racial abilities. However, a Naga doesn't have limbs so it would preclude casting spells with somatic components.

You need to be able to speak for spells with verbal components, and you need hands for somatic components.
You also can't cast spells with material components if your new form can't wear a spell component pouch (because it melds into your form).

A druid keeps his Wild Shape ability unless you cast Shapechange (which causes you to lose your supernatural abilities) but otherwise the same rules apply. Natural Spell only works with Wild Shape.

There is a feat for sorcerers to let Natural Spell apply to polymorph in Dragon Magazine somewhere. Mantle of Khyber or something like that iirc.

For your examples, Yuan-Ti and Demons/Devils generally have hands and can speak, so you can cast normally. Naga have no hands so you can't cast spells with somatic components if you're polymorphed into one.

Thanks, was a bit uncertain on what was retained. :)
