Arcane Lineage Boss List

King Slime

King Slime is more of a mini-boss, not as menacing as other bosses in Arcane Lineage. However, it's still a challenge for low-level players. Note that it doesn't yield soul points.

King Slime Location

King Slime spawns after 100 slimes are defeated on the server. It appears around the city nearest to the last slain slime, with a notification on the Quest Board. The quest involves two steps: finding and defeating the King Slime, with a 30-minute global cooldown.

King Slime Fighting Strategy

With a modest 400 HP (600 if Corrupted), King Slime summons additional slimes and employs poison-based AOE attacks. Prepare with potions and cleansing abilities to mitigate the poison. Focus on eliminating the summoned slimes first to secure a swift victory.
