ED balancers are easy solo

Just saying if you have any issue with them and you want that SSS relic just get wylder and solo it.

All what you need is to run away separating them one by one And once you get one down run again finally for the worm alway be away never ever be near that thing even it's blood AoE you can survive by being out of range, the only difficulty i encounter solo is their grap attacks and multiple plunge attacks,, if these two catches you GG but give 2 or 3 rounds and Also you can use solo play privileges like resetting that map untill you have super merchant to have extra wending grace .
