You are using 'feigned remorse'.

Your hand nearly fades out of view, making Amazon surprised as your serpentyne
meets its skin creating a nasty lesion.

You are prepared to do the skill.

You kneel down and beg mercy from Amazon who is convinced by your feigned
integrity. As Amazon approaches to help you up, you viciously pretend to offer
your hand, while you perforate its body with serpentyne. Amazon pukes out
blood and seems heartbroken and demoralized.
