MAXIMUM DAMAGE (outdated, read desc for build details)
2,135And they say STR builds are bad
DISCLAIMER: This is tool-assisted. I'm not gonna pretend I'm good enough to consistently get all these inputs and I didn't wanna have a bunch of tries for no reason, so I used Speedhacks to put the game at 0.25x speed so I'd have an easier time applying buffs, and still managed to mess up the order a bunch. That said, if you do everything right, you should be able to get this damage without speed hacks. If any of the visual aspects of the game look odd, the speed hacks are why, and you can tell the audio is completely distorted. I've tried many combinations and orders but this gave me the best damage out of everything I tried, which means there are some overwriting buffs I'm unaware of.
Everything Involved in order
Stats/Talismans:
99 STR/DEX, Quality Giant Crusher +25 (golems are weak to strike damage)
Kindred of Rot Exultation, Lord of Blood's Exultation, Dagger Talisman, Red Feathered Talisman (not used since my health didn't go low enough)
Commander Standard (+20% but it took too long for me to do everything so the buff went away before I got the hit so ignore this)
Bloodboil Aromatic (+35% physical)
Uplifting Aromatic (+10%)
White Mask (+10% from blood loss via Seppuku)
Lord of Blood's Exultation (+20% from blood loss via Seppuku)
Mushroom Crown (+10% from poison via Raw Meat Dumpling)
Kindred of Rot Exultation (+20% from poison via Raw Meat Dumpling)
Soul Stifler (+15% damage intake on the enemy)
Royal Knight's Resolve (+80% for one hit but this seems to affect crits differently and give more like a +35% or something)
Jellyfish (+20%)
Dagger Talisman (+17% on crits)
According to my calculations, it's supposed to deal even more than this even when considering for RKR and commander standard (more in the 86k range), but I'm unsure why it didn't. Oh well. Maybe I'll try this again one day when I wanna completely ruin my save file and just make buffs last permanently or something, cuz I think it's possible to go higher. Anyone else is welcome to try while using this as a reference.
Questions you might have:
Q: What about Madness buffs like howl and dumpling helmet?
A: Bloodboil seems to overwrite the howl and Idk why but I end up with less damage after dumpling
Q: What about Blue Dancer Charm?
A: It only takes effect under 25 weight, which Giant Crusher is already more than, so it's not gonna do anything
Q: What about Ritual Sword or Red Feather Sword talis?
A: These probably work but I haven't been able to get them to do more damage, the HP management is tricky.
