Control Shape Skill

Control Shape (Wis)
If you have the power to change your form.

Involuntary Change
You must make a check to resist involuntarily assuming beast form. If you are injured, you must also check for an involuntary change after accumulating enough damage to reduce your hit points by one-quarter and again after each additional one-quarter lost.

On a failed check, you must change into your beast form.

Voluntary Change
In addition, if you are aware of your condition, you may attempt to use this skill voluntarily in order to change to beast form, assume hybrid form, or return to humanoid form.

Action
Voluntary changes are actions.

Try Again
You can check to resist an involuntary change once each time a triggering event occurs.

You can retry voluntary changes to beast form or hybrid form as often as you like.
