Feat: Ostentatious Arrival

If the next action you take is to Manifest your Eidolon as a three-action activity, or to Cast a 3-action summon or incarnate Spell, the creature appears in an explosion.

All creatures in a 10-foot emanation around the creature you summoned or manifested except you take 1d4 fire damage per spell rank for a summon or incarnate spell, or 1d4 damage per 2 levels for Manifesting your Eidolon.

If the creature you summoned or manifested has the acid, cold, electricity, fire, sonic, or water trait, the damage is that type instead (or bludgeoning damage for the water trait). If the creature has more than one of these traits, you choose which damage type to deal.
