Water Form

You transform a willing creature you touch, along with everything it's wearing and carrying, into an amorphous blob of water for the duration. The spell ends if the creature drops to 0 hit points. An incorporeal creature isn't affected.

While in this form, the target's only method of movement is a swimming speed of 10 feet. The target can enter and occupy the space of another creature if that creature is a liquid entity itself (eg. Water Elemental). The target has immunity to non-magical attacks, crushing damage, and falling damage. The target can pass through small holes, narrow openings, and cracks wide enough for water to move through and is

While in the form of an amorphous blob, the target can't talk but can manipulate objects the same size as your blob, and any objects it was carrying or holding can't be dropped, used, or otherwise interacted with. The target can't attack or cast spells.
