Alas instead of victory I report a challenge run failure.
I played solo and wanted to kill all bosses and hang their trophies in under 100 days. I also set myself playstyle rules, no merchant, no farming, no cauldron (therefore no potions and recipe food) no movement penalty armour. Basically I wanted to see if light armour, lowish tier food and no potions could be enough to beat all bosses.

I killed all bosses except Yagluth.

On day 43 I summoned Yagluth.
I had:
padded helm level 2
fenris chest and pants level 2
Troll cape level 4
Iron mace level 4
Eikthyr power
Serpent meat, lox meat, cloudberry
Skills probly around 40 mostly

I failed hard and hard and hard, again and again. I only got him about one third down on health. I could have continued, it just would've meant going for more boat rides to get more serpent meat and hunting some more lox and then I could keep trying but not having a fire potion for protection is bloody hell, one hit sometimes can be more than enough to wipe me out, I have to be crazy precautions but the hustle needs to be kept up so he doesn't just keep regenerating. The concentration level was too much for me at that moment and I couldn't handle it. I may return when im fresh again but just wanted to give the heads up if anyone else is game to try this?

Ps. I have beaten Yagluth before many times. this is a challenge run I'm trying with the main big thing being no potions. It seems so far Yagluth is very hard to do without potions. I will try beat him on a fully geared character without using potions and see if gear could be a deciding factor to the no potions run.

Large set of tamed 2 star wolves shred yag in seconds if they're on him when he spawns. Whether you could find and breed 2 starts under 100 days though would be the only question.

Then there's the floor method some speed runners use too of course. Check it out on youtube.
