Does the language used in the Mighty Summoner feature, "Summoned OR Created", allow the ability to apply to a player transformed by polymorph?
Does polymorph, which reads, "This spell transforms a creature that you can see within range into a new form", count as creating a beast?
To determine if a creature was “created or summoned” by a spell we ask the question:
was this creature here before the spell was cast?
Now, say I cast polymorph on Jim. Was Jim here before the spell was cast? Yes. I have not created Jim, I have not summoned Jim. Jim’s been here the whole time. Mighty Summoner does not apply to Jim.
Polymorph is a Transmutation spell. It doesn't summon or create anything; it transforms one thing into a different thing.
