Moscovia dungeon quest

[Namine]

You can also try to borrow a battle custom pet such as Aliot, just try to attack enough to trigger pet to attack for you (or borrow a reflect gear, such as tormenting ghost, high orc shield, etc) and let the pet do it for you as you spam your (novice) potions.

As for the quest bug, I "completed" the quest warpped to Whale's Island while the monsters are um... alive. I was all prepared to fight them of course and fought them a few times, but the last time the monsters appear, I engaged them and during mid-battle when merman is still alive, I got warped out and quest completion \o/ so lol~
