Reactive Flesh

"“Something inside you feels wrong, as though your internal organs have been turned upside down. Queasy, you reach out to steady yourself and find your bones beginning to bend and give way under pressure. You slip and fall, a shooting pain travelling down your arm. The pain seems to trigger some kind of inbuilt survival response, and you find your body liable to balloon and retract in size, seemingly at random.” —In-game description"
