The most annoying debuff in the game is the Unquenchable Flames from the Ignis trash in Ulduar.
Nothing else I’ve healed through in the game has bugged me quite as much as this debuff.
Overall, healing Ulduar is fun… but Unquenchable flames is not fun! Why?
First, you can’t stop casting to drink between trash pulls very easily. With the nerf to spirit’s out of casting regen, stopping to drink is not as minor of a deal as it used to be.
Second, if you res someone and don’t top them off fast enough, they could die again. It’s been known to target the person we were resing and kill them. Which is annoying because then they have another repair bill and require another res.
Third, it can take a LONG time before it can be cleansed in the water. It just bounces around and does a ton of damage to people for a long time. It is annoying mostly because it takes us a while to get through trash, and it’s a large chunk of time when you can only have limited drinking and you have to be constantly vigilant. It also makes the rest of the trash pulls harder, and the Ignis trash is really hard enough without it.
It’s not impossible to heal through, it just drives me crazy.
