Leaping Assassin

You've learned the secret behind the silent air assassinations displayed by the assassins before you, gaining the following benefits:

You gain +20 movement

If you attempt to land on top of a creature, you can use your reaction to make a melee weapon attack, dealing Xd4 + piercing damage. X equals how many feet you've fallen, divided by 10. E.g. falling 20 feet means you deal 2d4 piercing damage to the target.

This effect stacks with sneak attack damage. You receive half of the total falling damage.

Roll to hit is the weapon you're wielding.
