Not a hundred, but around 30-40. Tried to use gnolls against my high-level PCs. They needed 17+ to hit the heroes, and did negligible damage when they did. I can definitely see how theoretically they are a threat, but in reality they were just somewhat annoying; really the whole fight was a waste of (a lot of!) time. No PC had GWM, so they weren't quite dropping them with one hit either.Anyone here actually throw a hundred enemies at their PC during 5E? I'm not counting swarms for the purposes of this question. I'm counting running a hundred enemies as a hundred enemies. I don't run 5E so I'll won't get that chance.
Tried it again with bugbears, same kind of result.
I like the idea of BA meaning monsters stay as a threat but that ends up being white-room theory; it feels very different when actually played out.
