Bone Dragon Abyss

Bone Dragon Abyss (70)
The area consists of a 10-man dungeon. The area sits in a canyon and was named due to the Wild Boss, final Dungeon Boss, and Hidden Boss were all Bone Dragons who are apparently brothers.

Bosses
Guardian Kaiwei: Guardian Kaiwei is the first Mini-Boss of the dungeon and wields a giant axe. He is a dragon guardian and has immunity to magic status effects. He only has powerful single target attacks and doesn't consist of any strong AoE attacks.

Bone Dragon Aldton: He is the final Boss of the Bone Dragon Abyss Dungeon who once was a red dragon. Due to being a dragon, Aldton has the ability "Dragon's Might" (although it isn't as strong as other dragons since it is an undead) which requires those who fight him to have a certain level of Spirit. If the Spirit stat does not meet the required level, players will not be able to use their full strength due to being "afraid". Due to being a Final Boss, he consists of multiple attacks.
 * Bite: A single target attack with a range of 12 units, does a lot of damage, and can cause a level 70 bleed. Aldton lowers his head before initiating this attack.
 * Wing Attack: He lifts his wing and attacks. The move is easy to spot, but it is very unpredictable due to the number of ways it can be used.
 * Tail Attack: It can be used in numerous ways: horizontal strike (covers a wide range making it difficult to dodge), whip strike (more flexible than the horizontal strike), or as a stab (it has a quick animation and is difficult to see making it the most difficult to dodge).
 * Breath Attack: It covers a reserve triangle area and the area is not fixed. The duration of the starting animation depends on the size of the area where the larger the area, the longer the animation. The amount of damage it deals is the same but lowers the player's health by 50% for 10 seconds.
