A challenging raid featuring Meradia, a formidable boss who wields both fire and ice elements across four distinct phases. Players must master elemental mechanics and precise coordination to overcome this powerful adversary.
Meradia
Meradia is a powerful elemental boss who controls both fire and ice. Throughout the encounter, she transitions between elemental phases, culminating in a dual-element form and finally splitting into two elemental clones that must be defeated separately.
Phase 1: Fire Element
4 Dangerous6 Mechanics7 Tips
HP: 999x 750x
In her first phase, Meradia wields fire-based attacks, creating flame fields and utilizing tracking lasers to pressure players. This phase introduces core mechanics that will be expanded upon in later phases.
Dangerous Mechanics
Cone Attack
Meradia holds her sword above her head with both hands (indicated by a yellow circle) before unleashing a targeted cone attack that deals extremely high damage and leaves a lingering fire field with significant damage over time.
Watch outDangerous mechanic — mistiming this can be lethal.
Skill Sealing Crystals
Meradia seals the skills of two pairs of players and spawns symbol crystals that must be destroyed. Each crystal can only be damaged by players with the matching symbol. The boss remains invulnerable until this mechanic is completed.
Watch outDangerous mechanic — mistiming this can be lethal.
900x Bar Mechanic
At 900x bars, Meradia teleports to the center and creates five outer zones separated by flame walls. Three zones (including the center) will be on fire, dealing heavy damage. Four sealing crystals with different symbols spawn that must be destroyed. After 15 seconds, all flame walls lower briefly, allowing traversal to break crystals.
Watch outDangerous mechanic — mistiming this can be lethal.
750x Bar Mechanic
At 750x bars, Meradia teleports two players to a chessboard dimension and spawns two chess pieces (pawns or knights) on the battlefield. Players must KO the chess pieces to make the spawns vulnerable, then defeat the spawns which execute specific mechanics based on their type.
Watch outDangerous mechanic — mistiming this can be lethal.
Other Mechanics
Tracking Lasers
Meradia fires lasers that track players, dealing moderate damage over time and leaving lingering flame fields. The laser line itself doesn't deal damage - only the impact area does. Players should focus on dodging while in the air to avoid damage.
Blade Swings
Meradia swipes her sword three times, sending flame slices across the battlefield. This pattern deals minimal damage in normal mode but can be dangerous in higher difficulties.
Tips
- Pair up at the start to efficiently break skill sealing crystals
- Remember which side of the chessboard you're on for positioning during mechanics
- Master the triple jump technique (launch attack + double jump) to save yourself in emergencies
- During tracking lasers, focus on dodging rather than DPS
- For the 900x mechanic, stay airborne to avoid fire damage when possible
- For the 750x mechanic, split into two parties based on your starting positions
- Knights always charge to their right at a 45-degree angle
Phase 2: Ice Element
4 Dangerous6 Mechanics7 Tips
HP: 750x 250x
After the 750x mechanic, Meradia transitions to ice-based attacks. Her abilities slow and freeze players, requiring different defensive strategies than in Phase 1.
Dangerous Mechanics
Ice Cone Attack
Similar to Phase 1's cone attack, but Meradia performs it three times consecutively. The ice cone slows movement speed significantly and eventually freezes players while dealing damage over time.
Watch outDangerous mechanic — mistiming this can be lethal.
Ice Wall
Meradia draws energy into her right hand and unleashes a shockwave that knocks players back and deals multiple instances of damage. Being caught by this attack often results in death due to repeated damage.
Watch outDangerous mechanic — mistiming this can be lethal.
500x Bar Mechanic
Meradia teleports to the center and randomly places players at the arena's edge. The arena is divided by walls of varying heights, and four symbol crystals spawn in the center zone. Players must navigate to break these crystals while avoiding falling icicles that can be used as platforms.
Watch outDangerous mechanic — mistiming this can be lethal.
250x Bar Mechanic
Meradia teleports a pair of players to the chessboard dimension and spawns either two rooks or two bishops. The teleported players must KO the corresponding chess pieces to make the spawns vulnerable, which then execute specific mechanics based on their type.
Watch outDangerous mechanic — mistiming this can be lethal.
Other Mechanics
Ice Crystals
Crystals spawn above players and deal moderate damage on impact. Players should move around to avoid them while continuing to deal damage when possible.
Icicles
Meradia spawns icicles above each player. Avoid overlapping with existing icicles to prevent unnecessary damage.
Tips
- Use super armor or dodge to avoid being knocked back by the Ice Wall attack
- During the 500x mechanic, use the triple jump to traverse high walls
- Be careful not to drop icicles on top of each other as they will explode and cause damage
- For bishops in the 250x mechanic, focus on breaking as many fireballs as possible to prevent black holes
- For rooks in the 250x mechanic, prioritize helping players who get bound by the binding attack
- Ice cone attacks leave persistent fields - avoid standing in them to prevent slowing and freezing
- Use icicles strategically as platforms during the 500x mechanic
Phase 3: Dual Element
1 Dangerous3 Mechanics7 Tips
HP: 250x 100x
After the 250x mechanic, Meradia harnesses both fire and ice elements simultaneously, creating dangerous environmental combinations that require careful positioning and movement.
Dangerous Mechanics
Dual Element Survival
Immediately upon entering Phase 3, Meradia drops three sets of icicles, then sets the ground on fire and raises fire walls. Players must drop icicles strategically and climb on top of them to avoid the burning floor.
Watch outDangerous mechanic — mistiming this can be lethal.
Other Mechanics
Fire Tracking Lasers
After the dual element survival mechanic, Meradia uses fire tracking lasers similar to Phase 1. Dodge these while dealing damage when possible.
Triple Slashes
Following the tracking lasers, Meradia performs the triple slash attack from Phase 1. This is a prime opportunity for high DPS.
Tips
- Ranged and aerial classes can damage Meradia from a distance during the dual element mechanic
- Avoid getting too close to Meradia while in the air as her aura causes instant death
- Don't place icicles where fire walls will spawn to avoid being burned
- The center zone may appear unaffected by fire due to a visual bug, but it is still dangerous
- Focus on bursting the boss down to 10% HP within one rotation of attacks if possible
- If you have revives available, you can strategically die to the tracking lasers to reset cooldowns for a stronger burst
- If the boss isn't pushed to 100x after one rotation, prepare for the mechanics to repeat
Phase 4: Elemental Split
2 Dangerous2 Mechanics4 Tips
HP: 100x 0x
At 100x bars, Meradia splits into two forms - herself and an elemental clone of the opposite element. Players must defeat the clone quickly to remove the boss's damage reduction, then focus on defeating Meradia herself to complete the raid.
Elemental Split
Meradia splits into two entities - herself and a clone of the opposite element. Both entities will perform attacks, making the battlefield chaotic. The boss has significant damage reduction while the clone lives, so the recommended strategy is to take out the clone first.
Watch outDangerous mechanic — mistiming this can be lethal.
Clone Respawn
If players take too long to defeat Meradia after defeat the clone, she will spawn another clone with a timer, reapplying her damage reduction.
Watch outDangerous mechanic — mistiming this can be lethal.
Tips
- The clone will always be the opposite element of what Meradia was before the split
- Focus on defeating the clone first to remove Meradia's damage reduction
- Be prepared for both fire and ice attacks simultaneously during this phase
- If you take too long, a new clone will spawn with another timer
