Some players are on MinMax overdrive
Brontosaurus is gargantuan, so you’d have to do a lot more than side step to get out of the way.
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.
That rule comes from Tasha’s Cauldron of Everything which is compatible with the 2024 update so it’s still a valid RAW interpretation according to WOTC.
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.
First of all, if I’m the DM, you don’t get to tell me not to use a rule.
Second of all, there will not be a situation where I use the 2024 ruleset. The 2014 ruleset is still around, and still usable, and anyone calling it outdated is an idiot.
Third, this is the only official rule given for this situation. If we don’t use it, there is no rule for falling on someone and we resolve it however I like. And since you just tried to interrupt my monologue, I’m not inclined to be generous.
