Location
Fushma wanders through the dungeon on the path indicated on the map.
The Battle
Fushma uses a short ranged physical attack and physical melee attacks. He'll run a couple times at the beginning of the fight, so take care that he doesn't drag you into mobs you may have left.
There are a couple of mobs that wander along the same path as Fushma. It is recommended that you kill them before fighting the boss.

Location
Rankar wanders through the dungeon on the path indicated on the map.
The Battle
Rankar has a long range fire AoE and a powerful short range physical AoE in addition to his melee attacks. These AoEs can be canceled by skills.
There are a couple of mobs that wander along the same path as Rankar. It is recommended that you kill them before fighting the boss.
Drops to Note:
Mold: Gale Dual Hammers (~17%)
Mold: Helmet of Lion Spirit (~17%)
Mold: Demon Panther Ring (~17%)







Location
Wyvern is located in the southeast corner of the map. There is one room east of his.
The Battle
Wyvern has two ranged mobs next to him. It's advised to lure them before beginning.
He has a long range single target magic attack, melee attacks, and a strong AoE physical attack. This AoE attack is not directional. Do not position the boss between the cleric and the tanker. The AoE, which has a radius of about 24 meters, will still reach out behind the boss. Turning the boss only brings the cleric closer. If the tank is between the cleric and the boss, the cleric may potentially stay out of AoE range.
Wyvern will also use an attack that curses the tank (increases damage taken by 20%). This debuff should be purified immediately.
Drops to Note:
Mold: Mystical Realm Pendant (~54%)
Mold: Annihilator of Souls (~52%)
Mold: Pants of Dragon Scales (~52%)
Mold: Necklace of the Legion (~52%)







Location
This boss is located on the northeast side of the dungeon, as indicated on the map.
The Battle
This boss is fairly easy. He'll use an AoE poison attack, but it doesn't hurt too much.
