Arcane Lineage Boss List

King Slime

While technically a boss, King Slime is more of a mini-boss, posing little threat to experienced players. However, lower-level players should proceed with caution. Note that this boss does not award soul points.

King Slime Location

King Slime spawns after 100 Slimes are killed on the server. It appears near the city closest to the last slain slime's location, announced on the Quest Board. The quest has two steps: Find King Slime; Kill King Slime. This quest has a 30-minute global server cooldown.

King Slime Fighting Strategy

King Slime starts with 400 HP (600 HP if Corrupted), the lowest of any boss. Its main attack involves summoning additional Slimes, which can overwhelm players. It also uses AoE poison attacks; bring potions and cleansing abilities. Its low health makes the fight straightforward: eliminate the Slimes first, then focus on King Slime.

Possible drops include: Random Tier 1 Equipment, Slime Buckler, Gelat Ring. Quest board rewards: Ferrus Skin, Potion, Small Health Potion, Essence, Gold.

Yar’thul, the Blazing Dragon

Yar’thul Location

Found deep within Mount Thul, an active volcano in the desert.

Yar’thul Fighting Strategy

Yar’thul has 1200 HP (1800 HP if Corrupted). The fight is a race against time due to its high damage output and Inferno/Burning effects. Phase two, triggered below 50% health, involves summoning meteors that inflict stunning and healing reduction. The Corrupted version gains lifesteal.
