Monks at level 12 decrease the fall damage they take by 70, which means they’re almost guaranteed to take max 20 points by falling from more than 200 feet (99,67% chance according to anydice).

That means level 12+ monks can jump from airships and other flying objects at basically no risk in order to infiltrate some place (especially way of shadow) or surprise their enemies.

Do what you want with this knowledge.
