Globular Weapons

You have learned how to form your body into any simple weapon you can think of. When in a humanoid form, as a bonus action you can turn any arm appendage you have formed at the moment into a simple weapon of your choice, you can do this to both of your arm appendages, but it takes separate bonus actions to do so. You cannot be disarmed of these arm weapons, and as a bonus action you can revert your arms back to normal. These weapons also disappear if you are knocked unconscious.
