This seems to be the same bug reported here:
https://forum.square-enix.com/ffxiv/threads/521618
I wanted to add more info to clarify what the bug is exactly, it should make it much quicker and easier to fix too.
It seems to me like the issue originates from a change to how mechanics that set your HP to a single digit are implemented.
Prior to patch 7.3
the game probably calculated how how much HP a person had minus some random single digit number, and then damaged the player for that amount. Leaving them with a single digit of HP. Example:
HP = 11014
random_digit = 3
damage = HP - random_digit = 11011
After patch 7.3
the game writes to the battle log "Your HP is now X."
which makes me suspect it instead just sets the HP to the random digit, without actually inflicting damage.
Getting damaged is a crucial part in A8S because it reduces a stack of final punishment.
Since the single digit HP mechanic implementation was changed, it no longer does that, effectively breaking the fight.
I checked this at least twice with a party of 8 people and I have screenshots of the battle log to show what I mean. (The J Storm's Gale force was bugged for all of us)
I imagine a solution would be to either make this an exception and not include it in the new implementation, or to add some boolean input to the HP setting function, that indicates that damage actually needs to be inflicted.
The group I'm in has been blind progging this for a very long time, we would appreciate being able to continue playing the game.
Date & Time: 15.08.2025 19:27 server time
Frequency: always (after patch 7.3)
World name: Ragnarok (chaos)
Character name: Baba Booey
Monster name: Brute Justice - specifically the 4 "J Storm" that spawn in the fight
Class/Level: MNK 60 (synced), and also everyone else in the party, so job is irrelevant
Party or solo: party of 8
In-game time: 5:55 (but again irrelevant, since it repeated)
Area and coordinates: alexander - burden of the son (savage)
Steps:
1. Go into A8S
2. Get to the "gavel" mechanic (no need to wait for the cast, it's enough that the tornados spawn)
3. Run into one of the tornados
Connection Specs and hardware software are irrelevant
This repeated for different ISPs in different countries with different PCs and OS (laptop / desktop)
This is clearly an implementation issue in the game post patch 7.3
