You summon fey spirits that take the form of beasts and appear in unoccupied spaces that you can see within range. Choose one of the following options for what appears:

• Two medium swarms of Summoned Spirits
• One large swarm of Summoned Spirits
• Two medium Summoned Spirits
• One large Summoned Spirit 

Each Summoned Spirit or swarm of Summoned Spirits is considered fey, and it disappears when it drops to 0 hit points or when the spell ends. Additionally, choose a type of creature that is summoned: aquatic, aerial, or terrestrial, with additional traits and abilities based on that choice.

The summoned creatures are friendly to you and your companions. Roll initiative for the summoned creatures as a group, which has its own turns. They obey any verbal commands that you issue to them (no action required by you). If you don't issue any commands to them, they defend themselves from hostile creatures, but otherwise take no actions.

A Summoned Spirit or Swarm has AC, hit points, attacks, Strength, and Dexterity determined by its size. Its Constitution is 10, Intelligence is 5, Wisdom is 12, and its Charisma is 8.
