While wearing this crown, you gain a greater degree of control of the shape of your body. Any character  with the Wild Shape feature is able to partially adopt a shape instead of fully transforming. 

The character is able to use a single ability score, ability or action of any beast she can normally change into. The character gains this ability without losing any of her other abilities, as she normally would in a shapeshift.

For instance adopting the tail attack of a giant crocodile, the character only partially changes into a crocodile; retaining her speech, her ability scores, yet gaining the tail attack.
Additionally the character gains 5 temporary hit points er CR of the chosen beast.

Activating this ability requires and consumes a use of Wild Shape.
This crown is only usable by characters worshipping Lurue.
