A rather open quirk that can have many effects and can also be gained by using scar items, in general only major missing parts can cause a negative effect which is a 40% increase chance to fail activities, smaller amputations do not effect the dinosaur. You can choose to do a major amputation or minor amputation, though there are some things that can not be missing at all: The torso, including organs, head and neck.

These count as major missing parts:
legs/arms, feet/hands, tail

These count as minor missing parts:
toes/fingers, tongue, eyes, claws, teeth

Some specific amputations have rules:
A dinosaur must have prosthetics if it can no longer support itself standing due to removal
A dinosaur having both eyes removed will gain blindness effects
Removing both claws and teeth/beaks will cause Defenceless trait. The dinosaur can no longer hunt, fish or battle.

Prosthetics are a free item to add to missing parts ( if you want to remove a tooth and add a gold one go nuts), you can draw your dinosaur without them, they are only required for the import image.
