Yeah pretty unlucky on the barbarian’s side

Literally a DC 10 to not be knocked prone and he had a +8 with advantage. 2 nat 1s later and he was knocked down.

The ranger landed a crit on his turn (which was next) and finished the Gibbering Mouther off, which let the barb stand on his turn without issue but he was blinded by one of the others.

To add more context, the barb had the highest hit points in the party. Everyone else was hovering around 30 for their max. Also the combat was 4 Gibbering Mouthers that started the fight spread out and nearly surrounding the party.

In general it was a hella cool combat that was teetering on the edge of oblivion for most of it. Which in all honesty made it that much cooler.
