Water Form

You transform someone's body into water. The target chooses what equipment turns into water and melds into them and what drops on the ground when they transform. You can still use effects of magical items if they have melded into you. While in this form you cannot wield weapons, but you gain a Bludgeon attack that deals 1d6 + strength modifier bludgeoning damage. The water maintains your general sillouette, but you can drop your own shape to seep through small spaces, so long as you keep yourself as one singular body of water. While in this shape you have immunity to poison damage, weakness to lightning damage, and resistance to acid, cold, fire, thunder, bludgeoning, piercing, and slashing damage. You can also move through enemies, and use the Disengage action as a bonus action. You are considered invisible while merged within bodies of water, your attacks are not hampered by being underwater, and you do not need to breathe while in this form. You gain a swimming speed equal to your walking speed.
