Telling people to play multiplayer in response to difficulty isnt a proper suggestion.

Parrying Soldiers does not give you enough time to get to their weak spot.

I agree the wisplight and wisptorches could use a small boost to their aoe

Difficulty spike is much higher than the very *very* marginal increase in armor/damage from the new gear, which can only be upgraded to rank 2, and is locked behind almost the entirety of the new biome's resource progression; meaning you have to complete nearly the entire Biome before you can even make the gear intended to help you survive the biome.
