Well I did it. it was a hell of a challenge but I actually managed to solo all of act one with no companions outside of dungeons where they're required. I had to experiment a lot and change my whole build a few times in order to win some fights. I also made it a bit easier on myself by parleying where I could ad. So here is the full rundown of my solo playthrough with my bimbo character Dumbun.
Okay so this was a tough one even at level 6. the door woman Azami was hands down the most difficult one to get past since she can do her encounter skill almost immediately, but with Das. trick followed up by shadow strike you should hopefully kill her before she gets it off. as for her lackeys it was a damage race I was just barely able to win. with the artificer you to you're summon and have it soak up damage while you tease him down. Same with Nakano only using damage instead. Here you switch from summon back to Das. trick two shot Miko with Das. trick and shadow strike finish Mai with an Assassinate. Finally Komari who was the easiest believe it or not she uses Kitsunesuki immediatetly use a Remedy and then burst her down with Das. trick and Shadow strike she folds like paper and doesn't do that much damage
not to tough at level 6. have high armor a buffed summon and heal equipped and just hold out
Hretha and Infrith are fairly easy but don't underestimate their damage out. If you can Burst Hretha and Gerrick Fast enough Infrith is just a big green Marshmallow. Argoth was no Challenge at all just one shot Benny with Assassinate and the Chief with Das Trick or if you want to go the other route just one shot him with an Assassinate. Now another thing I found with this dungeon is that in the camp you can fight a group of Guards open the the gate and then leave and comeback to finish the quest later. Do with that knowledge what you will
She's a pain in the ass. She's rathe tanky on top of being very damaging along with her warg I only just managed to beat them after my summon lasted long enough to take her out and the warg was low enough that I could finish it off.
