You turn the target into a watery, amorphous form. Both the target and its equipment becomes aqueous and translucent, as if made by water. While in this form, the creature can't take any actions, has a swimming speed equal to twice its walking or swimming speed, and can breathe underwater.
Additionally, they have resistance to acid, bludgeoning, piercing and slashing damage, and if they are not moving, they have advantage on Dexterity (Stealth) checks to remain hidden, and other creatures have disadvantage on Wisdom (Perception) checks to spot them.
