The Unending Coil of Bahamut (Ultimate) - Boss VFX + BGM 

I think it was an act plugin called hojoring, I doubt it's supported anymore. There's probably similar plugins that do the same thing but I don't know what they are, sorry. You could check XIVLauncher.

A cheat. You can report this player with the video link and get them banned. There are too many cactpot losers in FFXIV raiding these days that need the game to play itself for them

Its a disgusting crutch you don't need. People use these (not allowed) tools thru the nose then complain "its too easy" makes me physically sick.

@@filthycasualgaming9715 WoW Rejects and the like lol. It's one thing to use ACT to help improve ones own dps (and that of their team with consent) but its literally cheating to use these plugins.
