My understanding is the limit at 20d6 is intended to represent terminal velocity.According to a quick Google search, you fall 500 feet in a round, so unless someone has feather fall they go splat in a round and take 22 d6 damage, or 77 because I'd average it and I think the limit is dumb. However I'd also probably max damage after 50 feet so (5*3.5)+(17*6) for 120 points of damage. Which a high level fighter or barbarian may survive.
Is that good enough?![]()
Per What is Free Fall? A Quick Lesson in Physics | Head Rush Blog. this estimate is way too low as the human body reaches terminal velocity after falling about 1500 feet so damage should instead cap at 150d6. So I would accept your damage answer too.
Note that the duration of a round in D&D depends on the edition, 1e for instance uses 1 minute rounds, other editions use 6 or 10 second rounds. For editions with 6 second rounds, the rise and fall consumes more than one round (so the character should only be able to use ranged attacks or spells that round, not melee) and it might be ruled similarly for a 10 second round as the rise and fall takes nearly the whole round before the character lands and can act. I think though the level of abstraction we are dealing with makes this not matter.
