Oozeshape

Your amorphous nature allows you to temporarily assume the form of a true ooze. As an action, you can transform into a Gelatinous Cube for up to 1 hour or until you revert to your normal form as a bonus action.

While transformed, you gain the following benefits:

• Your size increases to Large, and your movement speed becomes 15 feet.
• Your AC becomes 6, matching that of a Gelatinous Cube.
• You gain the Engulf and Pseudopod actions of a Gelatinous Cube.
• You are considered an ooze in addition to your other creature types.
• You can move through gaps as small as 1 inch wide without squeezing.
• You gain blindsight 60 feet, but are blind beyond this radius.
  
  

However, you retain the following:

• Your own hit points and hit dice instead of using the cube’s.
• Your own mental ability scores (Intelligence, Wisdom, and Charisma).
• Your own saving throw proficiencies and skill proficiencies.
• You cannot speak, cast spells, or wield weapons and armor while in this form.

Once you use this feature, you can’t use it again until you finish a long rest.
