In D&D 5e, basically all PCs fit in on a 5 foot square. I want to figure out how much that 5 foot square can hold at end of turn by rules as written.
My first estimation is 3 people. Using the rule that allows creatures to use other creatures that are a size category bigger then them as a mount, allows for the situation: A centaur barbarian counts as large for carrying and pushing so with some plate armored fighter on top, duel wielding lances, a half-ling sits on the fighters shoulders, gets us to three.
That is 3, but can we get more?
