The Mutation Mind psychic archetype ability, Physical Mutation, doesnt seem to be a polymorph effect by default (meaning it will stack with polymorph effects).
However it has additional stacking effects that you get in place of phrenic amplifications as you level up.
One in particular, Enlarged Body(Ex) behaves "as enlarge person" which normally would make it a polymorph effect.
My question is: does adding Enlarged Body to your Physical Mutation ability make it a polymorph effect and prevent it stacking with other polymorph effects? Or does it continue to act as a physical change instead of a magical one?
Enlarged Body(Ex):
The mutation mind's body swells and stretches, enlarging her as the enlarge person spell but up to two size categories larger (maximum Huge).
