Explosive Metamorphosis
You use additional primal energy to transform, creating a burst of elemental energy to complement your transformation. If your next action is to cast a non-cantrip morph or polymorph spell, select acid, cold, electricity, or fire. Your transformation creates a 5-foot emanation around your new form that deals 1d6 damage of that type per rank of the spell. Each creature in that area attempts a basic Reflex save against your spell DC.
If your polymorph action had a trait corresponding to an energy type, you must select that one if possible. This action gains the trait corresponding to the energy type selected.
Traits
This indicates abilities from the druid class.
Spellshape actions tweak the properties of your spells. You must use a spellshape action directly before casting the spell you want to alter. If you use any action (including free actions and reactions) other than casting a spell directly after, you waste the benefits of the spellshape action. The benefit is also lost if your turn ends before you cast the spell. Any additional effects added by a spellshape action are part of the spell's effect, not of the spellshape action itself.
