Change Shape (2/Day). The aquado magically polymorphs into a beast with a challenge rating of 1 or less, and can remain in this form for up to 4 hours. The aquado can choose whether its equipment falls to the ground, melds with its new form, or is worn by the new form. The aquado reverts to its true form if it dies or falls unconscious. The aquado can revert to its true form using a bonus action on its turn.
Aquados are naturally skilled at training animals, but some learn druidic magic and natural lore. They dedicate themselves to protecting the beasts they raise and the balance of nature, acting as shamans among their ilk and wielding weapons made from water and ice. The magic holding such weapons together fades when the protector that created them dies.
