Why Play A Ghoran?

[Psyren]

Growing food out of yourself is fine, phrasing it in terms of an existing spell is easy, but the form change to growing food of yourself inherently brings up the fact that a creature cannot eat itself to survive. The Regeneration ability lets you regrow limbs, but I'd bet the vast majority of people would in fact bat an eye if you said a Troll, which needs to eat, can get by just eating their own limbs.

A Ghoran's goodberry SLA is magic.
A Troll's regeneration is not.
Simple.
