The Transfer dungeon's Abyss level has been cleared flawlessly and since I helped with the healing and commands on how they should fight the boss, it was much smoother for them to finish the dungeon without any casualties and minimal damage to the equipment. It was insignificant and the boss is not that strong, to begin with. The only thing that makes it a threat is that it can easily use an illusion that would allow it to attack while being safe from the attackers due to the illusion. Unfortunately for the boss, I already know the techniques, allowing for our easy clear.
