Elemental Swarm

When you cast this spell, you open a portal to one of the Elemental Planes and summon loyal elementals from it. The caster can determine which plane the elementals come from (Air, Earth, Fire or Water).

Once the spell has finished being cast, 2d4+4 mephits of your chosen type are summoned (Smoke Mephit for Air, Mud Mephits for Earth, Magma Mephits for Fire or Ice Mephits for Water). 1 minute later, 1d4 elementals of your chosen type will appear. After 1 more minute, a Genie of your chosen type will appear.

Once all of these elementals have been summoned, they will remain for the duration loyal to your commands, and will not harm you or your allies, even if they are charmed into doing so.
