Casting Time: 1 bonus action
Components: V, S
Duration: Concentration, up to 1 minute
You adopt the form of a swarm of creatures. The transformation lasts for the duration, or until you drop to 0 hit points or die. The new form can be any swarm of Tiny beasts whose challenge rating is equal to or less than 1. Your game statistics, including mental ability scores, are replaced by the statistics of the chosen beast, but you retain your alignment and personality.
You assume the hit points of your new form. When you revert to your normal form, you return to the number of hit points you had before you transformed. If you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. As long as the excess damage doesn’t reduce your normal form to 0 hit point, you aren’t knocked unconscious.
You are limited in the actions you can perform by the nature of your new form, and cannot speak, cast spells, or take any other action that requires hands or speech.
Your gear melds into the new form. You cannot activate, use, wield, or otherwise benefit from any of your equipment.
