Falling

When you fall, you immediately descend up to 500 feet at the end of your turn. If you're still falling on your next turn, you descend up to 500 feet at the end of that turn. This process continues until the fall ends, either because you hit a surface or the fall is otherwise halted.

If you hit a surface at the end of a fall, you take 1d6 bludgeoning damage for every 10 feet you fell. You must make a successful Fortitude Save equal to the damage taken to avoid landing prone.

While falling, you can use your reaction to grab onto something if a viable object is within your reach. Make a DC 15 Dexterity saving throw, on a success, you grab the intended object. Similarly, another creature can attempt the same Dexterity saving throw using their reaction to grab onto you if you're within reach, though the GM may require them to make a Strength (Athletics) check to keep themselves aloft or pull you to safety.
