Conjure Water Elemental

You call forth a water elemental guardian, gifted by The Tempest herself. Choose an area of water that fills a 10-foot cube within range. An elemental appears in an unoccupied space within 10 feet of it. For example, a water elemental springs from a nearby fountain. The elemental disappears when it drops to 0 hit points or when the spell ends.

The elemental is friendly to you and your companions for the duration. Roll initiative for the elemental, which has its own turns. It obeys any verbal commands that you issue to it (no action required by you). If you don't issue any commands to the elemental, it defends itself from hostile creatures but otherwise takes no actions.

The GM has the elemental's statistics.
