King Slime
More of a mini-boss than a true challenge, the King Slime is still capable of overwhelming low-level players. Note that this boss does not yield soul points.
King Slime Location
The King Slime spawns after 100 Slimes are killed on the server. It will appear near the city closest to the last slain slime's location. A notice on the Quest Board will announce the King Slime quest, which involves locating and defeating the boss. This quest has a 30-minute global server cooldown.
King Slime Fighting Strategy
The King Slime boasts 400 HP (600 HP if Corrupted), the lowest of any boss in *Arcane Lineage*. Its main attack involves summoning more Slimes, which can overwhelm players if left unchecked. It also employs AOE poison attacks, so potions and cleansing abilities are recommended. Its low health pool makes the battle straightforward. Focus on eliminating the summoned Slimes before focusing your attacks on the King Slime itself. Its AOE attacks only inflict poison, not direct damage, allowing for consistent attacks.
