    Ok, but hear me out:

    If you accelerate something into a freefall orbit, then it stands to reason that the projectile would deal falling damage (equal and opposite force, you know) which maxes out at 20 d6.

      If a character has 121hp or more they’re able to jump from a space station onto earth with like a super hero landing??

        In 5e yes. I think the theory is once you hit terminal velocity, you aren’t going to get any more damage from a longer fall.

        Fun fact, I actually did have a villain do exactly that in a campaign once. The party achieved a secondary win condition during combat and so the BBEG jumped off the top of the space elevator to escape.

          Wouldn’t jumping off the top of a space elevator just put you in orbit? Or, if by top you mean the point where the space elevator anchors to its counterweight, in orbit around the sun.

        theyd also need something to protect them from the friction and resulting heat of air brushing by at terminal velocity tho, i assume?

        oh no wait, im making it too realistic

          Piss hard so the reaction mass slows you down along with the cloud of expanding piss vapor.

          Terminal velocity for a human is not fast enough to cause air to heat up. You’d probably get frostburn instead.

            If you’re jumping from a space station then you’d be traveling at orbital velocity when hitting the atmosphere which is plenty fast enough to generate heat.

            Heating on reentry is actually due to compressing the air in front of you, not friction. Falling from orbitall height will absolutely cause you to heat up the air in front of you, even as the air paassing you by is doing you no harm.

            Though, if you smash into the atmosphere at orbital speeds, it’s probably going to do you some harm as it tries to force you back down to TV.

            Hold up. Didn’t some guy drop balls off a roof to show that things fall at the same speed?

              I recently had this explained to me, terminal velocity is falling versus the force of the air pushing back on you, right? In vacuum you just keep accelerating, in atmosphere the air pushes back against you falling, limiting your speed

              That force follows the rule that force (of air pushing back) is equal to acceleration (9.8m/s/s) times mass

              So different weights fall at different speeds.

              Half of the replies to me when I said what you said were

              Idiot, f=ma

              Or similar

              So, yes and no. Acceleration due to gravity impacts all objects equally. With no air resistance, on earth, everything speeds up at 9.8m/s/s. But, that “no air resistance” is a big asterisk. This is why, say, parachutes work. It’s also how we get terminal velocity. Often misinterpreted as “how fast you’d have to go to die from a fall” it’s actually “how fast you need to go before the drag from your air resistance is a force greater than or equal to gravity”

                Right. That all makes sense. So the air resistance is what is also causing it to heat up. I still don’t see why a person wouldn’t do that.

                  So, multiple options here. Skydivers regularly hit terminal velocity, as fast as they’ll go in atmosphere, before pulling their chutes. At these speeds, heat from friction isn’t enough to worry about. Once again though, if you’re coming down from space, that “in atmosphere” asterisk goes away. If you’re dropping from a satellite, you’re going at speeds necessary to orbit, and you don’t have anything slowing you down until you hit the atmosphere. Suddenly your terminal velocity is way lower than infinity, and the friction you’re feeling from the atmosphere is INTENSE, rapidly turning that speed into heat

                Well sure but I don’t think a human is shaped in a way that would really affect this.

        No. They’d need a pretty impressive jump height to slow down enough to leave orbit.

      Applying real world logic to game rules never works out.

      Also, you forget to take into account the weapon’s mass, form, structural integrity, the commoner’s reaction time, probability to fumble, the force of the wind, and probably a few dozen other factors that have an effect in the real world.

      Just don’t. It’s a game.

      If you can manage to get someone into freefall I’d allow it. But no, equal opposite forces doesn’t mean you roll dice the same lol. Your sword does not take damage when you attack with it.
