My wife and I play quite a bit of coop DST, but we had recently taken a break for quite a few months. We started playing again just last week and we're having a lot of trouble with Dragonfly.

Previously, this was a routine battle for us. We built a stone arena roughly 20x20 in size, wore marble armor/football helmets, tanked her melee attacks, and when she was about to rage, I would play the pan flute to settle her down.

However, now that we started playing again and we're running into a huge issue: playing the pan flute is not stopping her rage in time.

What is going on? I used to just hover my cursor over the pan flute and as soon as she was about to rage, I'd play the flute before she could even use her fire slam. This would prevent the fire slam, stop her rage, and we'd continue the battle in mundane fashion.

Nowadays though, I play the pan flute and often times she still does a fire slam, obliterates us with it, and then we run around in a panic trying to heal/play the flute again before we get wiped out.

Was this battle changed slightly? Was the pan flute nerfed? What are we doing wrong?
