This is regarding Prodromus, Herald of the End Times (normal difficulty). I encountered a strange interaction where the basic attack (the slow orb) was one-shotting my character with 8000 hp and high (but not maxed) resists in chaos.
This was very unexpected as I had been doing fine until this point and thought that maybe there was some mechanism or quest I had to complete before I could actually fight them. I did manage to figure out a way to navigate around the orbs and deal damage, but the severity of the hit seems unintentional especially on normal.
This is exactly what I felt when first encountering him (melee character) I got insta deleted within 0.5seconds of the fight, 1 shotted. This happened 3 times before I figured out how to fight him. My chaos resistance was around 45%, but he was still hitting for 8000damage 1 shot. I decided to cap my chaos resistance to 80% and used the chaos resistance ointment for extra overcap. That made it so I could survive an orb, but it still did around 7000damage.
I did manage to kill him after about 6-7 tries, it does seem very challenging on normal difficulty. I do think his damage could do with changing a bit to make it a bit more fair on normal. I found him harder then the final boss.
Noticed the same issue, keeps getting OS with 6khp, 86% chaos resist, 1200 armour, on normal.
Even in melee range, this boss only ever used the slow orb attack. The weirdest part is that the first few deaths, the highest damage taken on my char was 4k to 5k, so not my full hp.
Prod is likely flipped with with Ult version
according to Grimtools Normal Prod has way higher base stats than Ult, which doesn’t exactly make sense if accurate, so likely an entry mislabel in game files causing it
