Aqueous form

You transform a willing creature you touch into a pool of water for the duration. Any objects the target is carrying or wearing meld into its new form and are innaccessable, though it continues to be affected by anything it was wearing, such as armour. The spell ends if the creature drops to 0 hit points. While in this form the target gains the following effects:

• It gains a swim speed of 30ft and can move over or through other liquids.
• It is indistinguishable from a normal pool of water while it remains motionless and is invisible while underwater.
• It has resistance to nonmagical damge and has advantage on Strength, Dexterity and Constitution saving throws.
• It can enter and occupy the space of another creature and can move through a space as narrow as 1 inch wide without squeezing  .
• It extinguishes nonmagical flames in any space it enters.

While in the form of a pool of water, the target can't talk, attack or cast spells.
