King Slime
While considered a mini-boss, King Slime is not to be underestimated, especially by low-level players. Note that soul points cannot be obtained from 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 notice on the Quest Board announces the King Slime quest, which involves locating and defeating the boss. This quest has a 30-minute global server cooldown.
King Slime Fighting Strategy
King Slime has 400 HP (600 HP if Corrupted), the lowest of any boss. Its main attack is summoning more Slimes, which can overwhelm players. AOE poison attacks are also employed, so potions and cleansing abilities are recommended. Its low health allows for a relatively straightforward battle; focus on eliminating summoned Slimes before attacking the King Slime directly. Its AOE attacks only inflict Poison, not direct damage.
| Attacks | Energy Cost | Effect |
|---|---|---|
| **Slime Creation** | 1 | Summons a Slime to fight for King Slime. |
| **Crush** | 0 | King Slime lunges forward, attacking a party member. |
| **Poison Eruption** | 2 | King Slime throws out a burst of Acid, poisoning your party. This attack cannot be dodged or blocked. |
| **Scalding Spray** | 3 | King Slime erupts with boiling hot liquid, poisoning your party. This attack cannot be dodged. |
King Slime Drops and Rewards
Possible drops from King Slime include: Random Tier 1 Equipment, Slime Buckler, Gelat Ring. Quest board rewards for completing the King Slime event: Ferrus Skin, Potion, Small Health Potion, Essence, Gold.
Yar’thul, the Blazing Dragon
This fire-type boss utilizes fire and inferno-based attacks. Its resistance to fire and physical damage, coupled with weakness to Hex damage, significantly impacts strategy.
Yar’thul Location
Yar’thul resides deep within Mount Thul, an active volcano in the desert. Navigating the volcano's dark corridors leads to the Blazing Dragon.
Yar’thul Fighting Strategy
Yar’thul boasts 1200 HP (1800 HP if Corrupted). Its high damage output, coupled with Inferno and Burning effects, makes this a race against time. Phase two, triggered below 50% health, involves summoned meteors that inflict stunning and healing reduction. The Dragon Ring and Pristine-level accessories are highly beneficial. The Corrupted version gains lifesteal.
| Attacks | Energy Cost | Effect |
|---|---|---|
| **Inferno** | 0 | Automatically inflicted Inferno status effect at battle start. Undodgeable. |
| **Fire Claw** | 0 | Fire-imbued claw slash, dealing light damage. |

| **Blaze Eruption** | 2 | Damages burning targets and applies Inferno/Burning stacks. |
| **Magma Beam** | 4 | Charges a devastating fire beam (1 turn charge, massive damage on next turn). Undodgeable. |
| **Hellfire** | 1 | Unstoppable wave of fire, light damage and Burning stacks. Undodgeable. |
| **Armageddon** | 6 | Below 50% health, summons a meteor for massive damage, stun, and healing reduction. Undodgeable. |

Possible drops: Dragontooth Blade, Dragonbone Gauntlets, Dragonbone Spear, Dragonflame Shield, Memory Fragment, Soul Dust, Phoenix Tear, Resplendant Essence, Lineage Shard, Skyward Totem.
Thorian, the Rotten
Once an animal, Thorian is now a corrupted abomination resistant to most elements but heavily weak to Holy damage.
Thorian Location
Thorian is found in the Deeproot Canopy within the Cess Grounds. Head right upon entering the Cess Grounds.
Thorian Fighting Strategy
Thorian has 2600 HP (3900 HP if Corrupted). A key mechanic involves avoiding consecutive attacks of the same type to prevent 150% damage healing. Vary attack types. Exploit its weakness to Holy damage (135% damage increase). Below 50% health, it unleashes a devastating attack inflicting Plague, Curse, and Hexed (15-turn cooldown).
| Attacks | Energy Cost | Effect |
|---|---|---|
| **Cursed Wave** | 2 | Damages 3 party members, chance to inflict Curse. |
| **Overflowing Curse** | 0 | Minigame; failure inflicts Plague. Undodgeable. |
| **Cess Breath** | 1 | AOE damage and debuffs. |
| **Warped Crush** | 1 | Damages 3 party members. |
| **Blasphemous Obliteration** | 5 | Below 50% health, devastating AOE attack inflicting Plague, Curse, and Hexed. Undodgeable. |

| **Plague Rupture** | 2 | Applies a random debuff then massive damage scaling with debuff count. |

Metrom’s Vessel
Metrom’s Vessel, a Raid Boss, requires a Void Key (obtained from corrupted bosses) and spawns on a global timer.
Metrom’s Vessel Location
Location is announced server-wide after spawning.
Metrom’s Vessel Fighting Strategy
Metrom’s Vessel has 10,000 HP (15,000 HP if Corrupted) and significant damage negation. The fight is lengthy (30-60 minutes). Two phases exist with different attacks and mechanics. Phase one involves destroying wings to reduce damage negation; timing is crucial to avoid triggering phase two attacks prematurely. Shadeblades (200 HP minions) must be eliminated quickly. Oblivion (undodgeable, 50% max HP damage) is a significant threat. Phase two features wings with offensive and defensive modes. Consistent debuff application is key for efficient damage.
Phase 1 Attacks
| Attacks | Energy Cost | Effect |
|---|---|---|
| **Rendering Slash** | 0 | Damages and applies Weakness stacks. |
| **Deathbound** | 1 | Applies Sundered stacks to 2 random players. |
| **Eclipse** | 1 | Applies a buff to Metrom’s Vessel. |
| **Invoke Shadeblades** | 3 | Summons two Shadeblades (200 HP each). Undodgeable. |
