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 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 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.
| Attack | Energy Cost | Effect |
|---|---|---|
| Slime Creation | 1 | Summons a Slime to aid King Slime. |
| Crush | 0 | King Slime lunges, attacking a party member. |
| Poison Eruption | 2 | AOE poison attack; undodgeable. |
| Scalding Spray | 3 | AOE poison attack; undodgeable. |

Quest Board rewards for completing the King Slime event include:
Yar’thul, the Blazing Dragon

Yar’thul possesses 1200 HP (1800 HP if Corrupted). Its high damage output necessitates a swift victory. Most attacks inflict Inferno and Burning. Below 50% health, it enters a second phase, summoning meteors that inflict stunning and healing reduction. The Dragon Ring and Pristine-level accessories significantly aid in this battle. The Corrupted version possesses lifesteal.

Thorian, once an animal, is now a corrupted abomination resistant to most elements but heavily weak to Holy damage.
Thorian is found deep within the Cess Grounds in the Deeproot Canopy.
Thorian has 2600 HP (3900 HP if Corrupted). A key mechanic involves its passive negation: attacking twice with the same type heals it by 150% of the damage dealt. Vary attack types. It's heavily weak to Holy damage. Below 50% health, it unleashes a devastating attack inflicting Plague, Curse, and Hexed.
| Attack | Energy Cost | Effect |
