@Baraz The knocking down isn't 100%. Typically half of my party falls prone from the first jump. Unfortunately, I think you got super unlucky
Even if it did, this is addressed by spacing your party out. I'm fine with some encounters being incredibly lethal without foreknowledge. It's a game, so game-over then reload.

@Demoulius, I'm not Firesnakearies, but if the initial minotaur misses their attack then the rest is decently easy with some luck.
Use Fighter's Menacing Attacks that cause fear. If you use action surge and fear both minotaurs, that's a full turn where neither of them hit you.
Use hold person/web/other spells to restrain them
Use bane on them to reduce their likelihood of hitting.
Use potion of speed to increase your dps

The point is that just about every encounter in the underdark has this form of difficulty and the monsters are very...... Homebrew. They took the appearance and statlines from the monster and dident look at their attacks and abilities. For that they just fumbled something together.

Maybe not the point you're making, but there are a lot of people in this thread discussing the difficulty of the encounter. Larian, and all DMs, are allowed to homebrew monsters. (Again, I'll agree that the minotaurs jumping every turn looks silly)

I feel like I'm playing with an angry DM that just wants to kill my characters. :-(

Difficulty ties directly to available monster abilities. If the minotaurs didn't have this jump+knockdown ability, they'd be a cakewalk
