Overview

This guide covers the first two major encounters in the Sanctuary raid. Defeating each boss grants one loot box per party member, containing standard Sanctuary rewards (including gold and orange bracelets) but excluding the Ludra weapon, so if you're aiming to maximize your efficiency and get raid-ready faster, you might consider whether to buy Aion 2 Kinah to properly gear up beforehand. These bosses feature HP-based phase transitions, meaning the order of mechanics varies with your group's damage output. This guide explains each mechanic individually.

Prologue: Central Abyss Fusion Reactor

Location: Immediately upon entering.

Loot: None. This is a gatekeeper event.

Mechanics:

The reactor alternates between a point-blank donut AoE and a large X-shaped AoE.

Constant waves of trash mobs spawn during the fight.

Periodically, a message announces an Auxiliary Fusion Reactor has appeared (Left, Right, or Center).

This reactor shields the main boss.

Pre-assigned party members must use the jump pads on the sides to reach and destroy the auxiliary reactor, removing the shield.

Strategy: Rinse and repeat while handling adds until the main reactor is destroyed. A portal will then appear.

Trash Duty & Platform Buffs

After the reactor, the raid splits:

Group 1: Teleports to First Boss.

Group 2: Teleports to a platform area.

Platform Group's Role:

Once Group 1 engages their boss, trash packs spawn on the Left, then Middle, then Right platforms in a repeating cycle (two waves per cycle).

After each two-wave cycle, a crystal appears. Interacting with it grants buffs (Heal-over-Time, Damage Boost, Movement Speed) to the group fighting the boss.

After Boss 1 dies, the roles reverse: Group 2 goes to Boss 2, and Group 1 handles the platforms.

First Boss: The Corruptor

Persistent Mechanic: The Purple Circle (DO NOT FAIL)

A party member receives a growing pink/purple circle.

They take sustained damage. When the circle completes, the debuff transfers to another player standing inside the circle.

CRITICAL: If no one is in the circle when it completes, it creates a progressively expanding purple AoE puddle on the ground that deals heavy damage

WIPE CONDITION: If three of these puddles are ever placed on the ground, the boss enrages and wipes the raid.

Common Rotating Mechanics:

Tank Buster + Patterns: A hard-hitting, sidesteppable tank attack, followed by a cross-shaped, then a plus-shaped AoE.

Safe Cone & Line AoE:

The boss casts an AoE covering the entire arena except a thin cone behind him. This cannot be blocked/evaded and is a one-shot.

Simultaneously, one player (marked by a green health bar and target icon) is targeted by a red line AoE.

The line snapshots 2 seconds before firing. Aim it away from the safe cone, then move into the safe spot.

Stacking Donuts: Each player gets a red donut AoE that erupts into a jumpable ring. Stack the group together before they detonate to overlap the safe spots.

HP-Based Phase Mechanics:

At ~75% HP: Stagger Lock & Cardinal Split

Boss locks stagger, teleports center, and warps each player to a cardinal direction (N, E, S, W).

One player gets a stack marker. The boss does rotating cone and pulsating donut AoEs.

Strategy: Everyone must group up on the boss while avoiding AoEs. Spam mitigations and heals. Avoid being hit by two AoEs simultaneously.

After 75% (if not yet at 50%): Poison Puddles

Each player drops an AoE that leaves a damaging poison puddle for ~30 seconds.

Strategy: Run to the edge of the arena to drop puddles, then return to DPS.

New Ability Post-50%:

Boss gains a two-part frontal/back attack: a sustained laser at the rear and a heavy point-blank AoE at the front.

At ~50% HP: Arena Division

Boss locks stagger and divides the arena into four quadrants with line AoEs.

Strategy: The entire group and tank should move the boss to the South quadrant.

Crossing the dividing lines deals heavy damage (but is possible if someone gets separated).

After division, the boss:

Jumps to tank (point-blank AoE).

Targets all players with poison puddle drops. Drop these clustered near the edge.

Executes cross and plus AoE pattern.

Does the red donut pulsating AoE.
This cycle repeats twice unless you push to 25%.

At ~25% HP: Monster Circles

Boss jumps to center, spawning four circles with monsters inside.

Random players (can be the same one twice) are marked with a line AoE.

They MUST aim this line to kill the monsters in the circles.

Failure spawns a black puddle that counts toward the 3-puddle wipe condition.

Note: The line can be dodged or blocked, but timing may be tricky with high ping.

Final Phase: Boss loops basic mechanics until defeated.

Second Boss: The Soul Reaper

Persistent Mechanics:

Purple Lasers: Straight-line AoEs sweep the arena from North or South. Moderate damage.

Dash & Smash: Boss dashes at someone, then marks and jumps at another player, slamming its weapon down with a point-blank AoE (dodge to avoid stun). When it retrieves the weapon, a white, jumpable ring AoE appears at the impact point.

Signature Mechanic 1: Spirit Cleanse

Boss flies to center, becomes untargetable, and creates a damaging black portal below it.

Spirit mobs spawn around the arena. Some die in 2 hits, others in 8.

Strategy: Split raid into two teams to clear spirits, moving clockwise and counter-clockwise from the South.

White Triangles: Two damaging triangles sweep from the South. If they touch a spirit, it explores and fears the entire raid for 3 seconds.

Safe Spot & Heal Check: After all spirits die and triangles vanish, a white safe circle appears in the center. The entire group must stack here while the boss does a heavy room-wide AoE. The safe spot makes the damage healable—mitigate and heal through it.

Variant (Second Occurrence): Red (look at) and Blue (look away) orbs appear in the safe area between the triangles at the end.

New Abilities After First Spirit Cleanse:

Orb Towers: Two towers spawn with floating orbs. A player must stand in the tower's circle and jump into the orb to absorb it before it hits the ground (heavy raid damage if failed). One player can absorb both.

Chasing Scythes (After Second Cleanse): Small spinning scythes chase two players. Kill them while kiting.

Signature Mechanic 2: Soul Crystal Invulnerability

Setup: Boss targets all players with a large red cone AoE and spawns Mortal Soul Stones around the arena's edge.

Crystal Buff: Breaking a crystal while inside its AoE grants 4 seconds of damage immunity.

Intended Strategy:

Group stacks.

Each player stands by a different crystal within the cone.

Break crystals just before the cone resolves to gain immunity.

Refresh the buff by breaking new crystals before it expires, surviving the boss's subsequent heavy room-wide AoE. This typically requires 2-3 crystals per person.

Common Cheese Strategy: Have everyone except the Cleric die. The Cleric breaks crystals alone to maintain immunity, then resurrects the raid after the mechanic.

Post-Crystal Orb Gaze:

Three orbs appear in rapid succession. You must look at (red/eye) or look away from (blue) them in the correct order.

Tip: If unsure, position your camera to fail only one orb (failing one is survivable).

After the orbs, a donut AoE occurs. This sequence may repeat if DPS is slow.

Cleric Note: This is the ideal time to use Mass Resurrection if using the cheese strategy.

Final Phase: Boss loops through all mechanics until defeated, and for players looking to expedite their gear upgrades for future attempts, I highly recommend MMOEXP as a trusted source to buy Aion 2 Kinah.
