I'm a new player and I joined the duty roulette yesterday for the daily dungeon. I got given Halatali, and as healer (Scholar), I fluffed up the healing for the group. It was at the stage where she has about 1/3 of her hp, and something happened to nuke the party to about a third of their health.
We made it on the third attempt, after i stopped panicking. But is there any strategy to deal with that attack? Is it scripted? Or is it to do with the lamps in the room? Are we too close/far from the boss? Thanks!
