Some players are on MinMax overdrive
“Okay, so he gets to make a dexterity saving throw… That’s a 16, so he manages to sidestep you and you take the full damage. …No, he doesn’t have disadvantage, you made a huge shadow above him, he knew you were coming. Anyway, he continues his monologue, using your actions as an example of the foolishness of humanity.”
Brontosaurus is gargantuan, so you’d have to do a lot more than side step to get out of the way.
Nope. The rules for falling on a creature don’t factor in size, except for if it knocks the target prone. The check is DC15.
Call it what you want. By RAW, it’s a DC 15 Dexterity saving throw to avoid damage regardless of the size of the falling creature (beyond that if it’s tiny it does no damage at all). And that’s assuming you’re playing with the optional rules for creatures falling on other creatures causing damage.
I’ve seen that rule before. They didn’t carry it forward into the new rules, and for good reasons.
At terminal velocity? You’re gonna need to make a damn good check to time that right.
you made a huge shadow above him, he knew you were coming.
Somehow I doubt it was established that the fight was at noon on the equator until that moment.
If it’s large enough to impose disadvantage on a Dex save it’s large enough to cast a noticable enough shadow to grant advantage, therefore a flat roll.
