Arcane Lineage Boss List

King Slime

King Slime Location

The King Slime spawns after 100 Slimes are killed on the server. It appears near the city closest to the last slain slime, announced on the Quest Board. The quest has two steps: find and kill the King Slime. This quest has a 30-minute server-wide cooldown.

King Slime Fighting Strategy

The King Slime has 400 HP (600 HP if Corrupted), the lowest of any boss. Its main attack is summoning Slimes, which can overwhelm players. It also uses AOE poison attacks.
