Conjure Spirit Jelly

You summon a spirit of water taking the form of a giant ghostly jellyfish in an unoccupied space you can see within 90 feet. While summoned, the jellyfish acts on its own initiative and will float in place periodically pulsing with Soothing Water, healing any creatures friendly to you within 10ft of it for 2d12  hit points. The Spirit Jelly will also lash out at enemies within 10ft of it with it's stinging tentacles for 4d4 lightning damage.

The Spirit Jelly is ethereal and cannot be targeted or damaged.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the healing done by Soothing Water increases by 1d12  and the damage done by its tentacles by 1d4 for each slot level above 5th.
