Raid Bosses

Phase 1 (100%–50% HP): Gorath attacks normally every turn. Every 5th hit triggers World Crush, an AoE strike that deals 150% ATK to the entire raid for that tick.

Phase 2 (50%–0%): Gorath activates Absorb Shield — absorbs the next 1,200 damage dealt to him. After the shield breaks, he retaliates with a 200% ATK strike. Burn through the shield quickly in coordinated groups.

Phase 1: Standard attacks. Shadowmaw has a 20% chance to apply a poison stack per hit — each stack deals 2% HP damage per turn, stacking up to 10 times.

Phase 2 (66% HP): Shadowmaw gains Cursed Scales — all physical damage is reduced by 30%. Magic-heavy builds (Blood Mage, Arcane Sprite) gain a significant advantage here.

Phase 3 (33% HP): Death Breath — a channeled AoE that deals 80% HP damage if not interrupted within 3 ticks. High-ATK players must burst through 33% HP to interrupt it.

Passive — Soul Drain: Every attack on the Empress heals her for 1% of damage dealt. This means the raid must sustain damage output; stopping to conserve stamina gives the boss significant healing.

Phase 2 (50%): Empress's Curse — debuffs all attackers with −20% ATK for 2 turns after dealing damage. This mechanic punishes high-frequency attackers; timed burst attacks are more efficient in Phase 2.

Phase 1: Moros cycles between normal attacks and Tidal Wave — a 2-turn charge that deals 300% ATK AoE. Inflicts a 3-turn DEF debuff on all hit targets.

Phase 2 (50%): Flood Tide — Moros splits into two HP pools. Each pool must be reduced to zero independently; killing only one causes the other to absorb the fallen pool's remaining HP.

Phase 1: The Archon applies Hellfire burn on every attack — 15% HP per turn for 3 turns. Life steal does not counter this debuff (true damage type).

Phase 2 (66%): Infernal Aegis — the boss becomes immune to physical damage for 5 turns. Only magic-based skills and Blood Mage AoE can deal damage during this window.

Phase 3 (33%): Apocalypse Countdown — a 10-turn timer. If the boss is not killed within 10 combined raid actions, it deals 99% HP damage to all active attackers. Maximum raid coordination required.

Passive — Void Absorption: The first 500,000 damage dealt to Keth each raid is absorbed and converted into ATK buffs for the boss. Only after 500,000 damage does normal damage reduction begin.

Phase 2 (50%): Event Horizon — any player who deals over 50,000 damage in a single attack triggers a 3-turn Silence effect on themselves. Burst damage must be paced carefully.

The hardest raid boss in Aeternum. Vreth has 4 phases, each with unique mechanics. Phase 1: high DEF + AoE every 4 turns. Phase 2 (75%): grows wings — gains +20% ATK and +30% dodge. Phase 3 (50%): Mountain Fall — deals 50% HP to the top 5 damage dealers in that raid session. Phase 4 (25%): Final Breath — deals 80% HP to all if not killed within 5 turns.

Unlock condition: Available only after a server-wide community quest chain is completed (roughly twice per year). Defeating Vreth earns the permanent Dragon Slayer title.

Phase 1: Valcor charges Lightning Core — after 20 hits by any player, discharges for 200% ATK AoE to all attackers that turn.

Phase 2 (60%): Storm Shell — absorbs all damage into a growing counter. At 200,000 absorbed, discharges for 150% ATK to the highest-damage contributor.

Phase 3 (30%): Titan's Wrath — Valcor doubles attack speed. Every player's next attack has a 30% chance to be reflected back. High-dodge characters (Shadow Assassin, Moon Warrior) have a major advantage here.
