Conquer the Bosses of Arcane Lineage: A Comprehensive Guide

Arcane Lineage presents a diverse range of bosses, from easily soloable encounters for newcomers to incredibly challenging battles requiring multiple coordinated teams.

This guide will equip you to face these formidable adversaries.

Arcane Lineage Boss List

King Slime

While technically a boss, King Slime is more of a mini-boss, posing a manageable challenge, even for lower-level players. However, it's not entirely trivial. Note that soul points are not awarded for defeating this boss.

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. A server-wide announcement on the Quest Board signals the King Slime quest's activation. The quest involves two steps: locating and defeating King Slime. This quest has a 30-minute global cooldown.

King Slime Fighting Strategy

King Slime boasts 400 HP (600 HP if Corrupted), the lowest of any boss. Its primary attack involves summoning additional Slimes, which can overwhelm players if not managed. AOE poison attacks are also employed. Potions and cleansing abilities are recommended. Its low HP allows for a relatively straightforward fight. Focus on eliminating the summoned Slimes before concentrating on the King Slime itself. Its AOE attacks inflict Poison but don't deal direct damage.

King Slime Drops and Rewards

Defeating King Slime yields:

• Random Tier 1 Equipment
• Slime Buckler
• Gelat Ring

Quest Board rewards for completing the King Slime event include:

• Ferrus Skin Potion
