You change the prosthetic of a willing creature you touch. When you cast the spell, choose one of the following options, the effects of which last for the duration of the spell.

Magic Conduit. You integrate the arcane focus, druidic focus or holy symbol you use as material cost into the prosthetics. The wearer can use the prosthetics as a focus for their spells, depending on the type of focus that was used.

Change Appearance. You transform the prosthetics appearance. You decide what it looks like, including its size, weight, coloration, and distinguishing characteristics, if any. You can make it appear as any limb of another any race, though none of your statistics change. It also can't appear as a limb of a different size category than the wearer, and its basic shape stays the same. At any time for the duration of the spell, the wearer can concentrate on it for half a minute to change the prosthetics appearance in this way again.

Natural Weapons. You transfrom the prosthetic to claws, fangs, spines, horns, or a different natural weapon of your choice. The prosthetic counts as a natural weapon and prosthetic for any purpose. Its strikes deal 1d8 bludgeoning, piercing, or slashing damage, as appropriate to the natural weapon you chose, and you are proficient with your prosthetic strikes. Finally, the natural weapon is magic and you have a +1 bonus to the attack and damage rolls you make using it.

Firm Leg. You strengthen the prosthetics ability to stand firm on the ground. If an effect moves the wearer against its will along the ground, it can use its reaction to reduce the distance it is moved by up to 5 feet. Additionally the wearer has Advantage on any Strength Saving Throw against being pushed.
