Polyguise

When you complete this conjugate and touch a willing biological creature, you can change its face to resemble any imaged face of their species. Other distinguishing features like skin tone and the sound of their voice can be similarly altered.

As with any genetic alteration, the change is permanent, until the effects can be reversed by this conjugate or a schema that restores your original appearance.
