Frequency: Once
World name: Balmung
Character name: Ludo Vician
Retainer name: N/a
NPC name: N/a
Monster name: Orthos Fitter
Class/Level: MCH | 90
Party or solo: Solo
In-game time: N/a
Area and coordinates: Eureka Orthos, Floor 97
Housing: N/a
Steps:
1. Use a Protomander of Lethargy on a floor on which an Orthos Fitter appears
2. Approach a room that contains an Orthos Fitter
*: For context, under regular conditions the Orthos Fitter has a cast bar for its roomwide AoE Unholy, and you can see a visual casting effect begin on the monster as it is preparing to cast Unholy. But, when the Lethargy debuff has been applied with the Protomander of Lethargy, it appears to instantly cast Unholy with no visual indicator that it is preparing the cast when the player approaches the room in which the Orthos Fitter appears.

The second clip is mine, still salty that it cost me the run. My guess is that happens if Lethargy was used during the cast of Unholy or/and the mob was unloaded from the screen. I don't know if the second part plays a role but looks like it happens to Fitters that are not close to a spawn room.

I also suspect that if they are not loaded when they start the animation both castbar and the glow of the casting animation don't show up when you get into range. Happened to me on floor 98 too. This entire piece of content is full of bugs.
