Hall of the Abyss level 56
A powerful boss indeed. The minions, however, are most dangerous. The boss summons the minions which attack the victim (the boss calls out the name of the victim).
Tip: If you character’s attacked by the minions, you need to run around the room perimeter until they’ve switched to another victim. If the tank is the victim, he/she needs to run in small circles so the party could attack the boss. You need to have a good stock of healing herbs. In case the healer is the victim, he/she will not be able to heal the tank and other party members.
Party members: Tank (knight or blade dancer/sword singer ), 2-3 warriors, healer, phantom summoner/necromancer/elemental summoner
Weapon: Grade B for the attackers
Armor: Grade B for the tank
Accessories: Any, as most damage is done with P. Atck.
