is 1d6, plus 60 ft to reach 90 ft makes it 7d6 - the last max possible using fall damage - and at 130 - my best case scenario guess - it's 10d6, a Max Damage of.60 Bludgeoning Damage.ok, there's a bit of fall off (heh) but it's still an interesting idea. The Falling Damage Rules though state that an object that is 50 pounds only needs 40 ft to start dealing damage. That still only travels 90ft, but does increase the damage to 9d8 (1d8 plus 8 levels above 1st level spell slot) for a Max Damage of 72 Bludgeoning Damage. If it does go 130 ft up, and THEN starts falling, it'd hit with a Fall Damage Dice Pool of 7d6, for a Max Damage of 42!įinally, just for fun, if you use a 9th Level Spell Slot on Catapult, that means you can use an object that is 9 X 5 + 5 pounds, or 50 pounds. Unless the spell just causes the object to STOP moving AT ALL after 90 ft, then it should continue upward for.I don't know, that's more complicated than I can do, but I think the rock MIGHT have enough leftover energy to POSSIBLY be able to reach at least 120 to 130 ft up. (70 ft is 1d6, 90 ft is 3d6 so 100 ft is 4d6) That should be easy for an object moving at 10 mph, even if it's initial momentum - the spell - is no longer acting on it, as the energy to move the rock is still there. So long as it can reach 100 ft, only 10 more feet, it's MAX damage will match that of Catapults at 24. (70 ft minimum plus 20 ft to reach 90 ft) that's only 18 MAX damage, but that's only if the rock stops AT 90 ft.

So, if the rock that is launched straight up needs 70ft of DOWN to gain 1d6, that sounds like a net loss, BUT so long as the rock continues from the 90 ft - which means it's now at 3d6. The spell itself does 3d8 Bludgeoning, for a max of 24 damage.

The question then becomes this: After the initial 90 ft that we get for free thanks to Catapult, how far will said object go NOW, traveling at roughly 10 miles-per-hour until gravity catches up to it once again? Here's the thing though that five-pound-rock is STILL moving after its initial push of 90 ft, as it hasn't HIT anything yet from going straight UP.

Weights for common objects can be found in the Equipment chapter of the Player's Handbook. An object traveling 90 ft in at most 6 seconds is traveling at least 10mph.
