I quick traveled to Shearpoint and saw a dragon perched on the Word Wall. Well I attacked it with arrows and it ended up crashing near the wall and I finished it off with arrows. I walked up to it to get its soul and woke up Krosis. I started using my bow on him but it had no effect at all. Again my bow has 15 points fire damage and I was adding a 17-25 point poison damage potion to each shot. Nothing. After about 20 hits with the arrows, and running low on health I charged him with the Nightengale blade. Well it did damage him but he got me before I could finish him off.

I repeated this three times, each time with the exact same results.

Only mods I use are a few graphic mods like red hair and no more blocky faces, and that’s about it (old PC can’t do much else).

So, is this a feature? Is Krosis immune to arrows, or is his AR so high that the arrows were only doing maybe 1 point of damage and I couldn’t tell. I thought the fire would at least do something to him. Without any arrow perks my bow damage is only around 21.

Thanks.

I had something like this with Volsung. I found it his hit box was extremely tiny. So much so that arrows would "bounce" off him and not cause any damage.

I'm not sure if it's a bug or a feature, but I experienced a similar thing. He dodged everything I tried to hit him with, so finally I summoned a Bound Bow and tried that. None of my arrows seemed to have any effect on him, even when it looked like they hit him.

At one point during the battle he slid far down the hillside and came to a stop, just hovering in place, facing me but not fighting back. I tried again to shoot him, and this time it worked. It felt like a cheap victory because I knew he had been glitched from the moment he fell down the slope.

Maybe you could try to give him an innocent nudge over the cliff next time you try to fight him?

I had an issue with Krosis wherein after I killed him I couldn't find his corpse/ashes so maybe he's buggy in general.

Detect undead... Best glitch killer in the game.

I still haven't found that spell and I have a thing about buying spells since I'm not a true Mage, but I may buy it soon because I'm about tired of waiting.

Three things that I have used to fix bugs are Blizzard (killed enemy stuck underground), Detect Life (Saw enemy that was underground), and Detect Undead (Saw a skeleton that was behind a wall).

Didn't someone say once that Krosis is immune to fire due to his protection spells?

he is immune to fire and is one tuff SOB. first time I came across him, I nearly jumped to my death in a firey plunge for safety.

He's no push over thats for sure. I usually take him on close with weapons. I think he is almost immune to frost as well.

Probably casts wards on himself against arrows.
