Jump distance increases by 5 feet.
By Tucking and Rolling, you can remove up to 10 feet of fall damage from a fall. 
If you intentionally fall at least 10 feet onto a creature, as a reaction you can make a melee attack against them with an unarmed strike or a weapon you are holding. You have advantage on the attack, and can add damage to the attack equal to the damage you take from the fall.
