Hold Wild Shape

For the duration of your Wild shape you can freely transform in and out of the same beast form without expending another use of the Wild Shape feature. This effect is lost if any of the following conditions occur. 

• The number of hours you can stay in beast form passes, regardless of what form you are in.
• You expend another use of Wild Shape to transform into a different creature.
• You cast magic outside of being in your beast form.
• Your beast form is reduced to 0 hit points.
• You fall unconscious, drop to 0 hit points, or die.

The remaining hit points the Wild Shape form has is kept the same regardless of transforming between entities (if the Wild Shape form takes damage, that damage is retained when transforming back into the Wild Shape form.) Conditions such as blinded, charmed and frightened are retained, no matter what form your character is in.
Using this feat to transform between beast form and normal form requires an action (or a bonus action if you are a Circle of the Moon druid.)
