Cermet Pile

AoE/Cleave

The boss will occasionally attack to its front with a cleave attack that deals moderate damage. This attack is untelegraphed, so the Tank should face the boss away from the rest of the party for the duration of the fight to avoid hitting them with Cermet Pile.

Garlean Fire

AoE

Targets a random player and fires a sequence of circular AoEs in their direction. Move out of the way to avoid.

• Subsequent uses of this attack will increase the number of AoEs that are simultaneously fired.

Rearguard Bit

AoE

The Magitek Bits in the back of the arena will begin firing line AoEs. These will go off every few seconds, so be mindful of your position as you dodge the following attack. After the Bits are activated, they will fire line AoEs for the remainder of the fight.

Rearguard Mine

AoE

Mines will begin moving slowly from the left and right side of the arena to the opposite side. Coming into contact with these will cause them to explode after a short delay, dealing high damage in the area. If you run into one, quickly move out of the area to avoid its explosion.

Circle of Death

AoE/Knockback

A point-blank knockback AoE around the boss. Move outside of the telegraphed area to avoid this attack.

2-tonze Magitek Missile

Stack Marker

Targets a random player with a stack marker. Group up on the affected player to spread out the damage of this attack.

Magitek Bits - Chain Mine

AoE/Knockback

Magitek Bits will spawn around the edges of the arena and create straight line AoEs that knock back players that come into contact with them. Keep this in mind when preparing to deal with the boss's next mechanic.

Magitek Missiles

AoE/Special

A Pillar will appear on the arena that at least one player needs to stand in to prevent high party-wide damage. This can be tricky to get to during Magitek Bits, so be sure that the party is spread out so that at least one player is close enough to the Pillar when it appears.

• Later in the fight, two Pillars will spawn together. These will both need a single player to stand in them to prevent party-wide damage.

Chainsaw

Tankbuster

Begins charging an attack to Grynewaht's front, dealing continuous damage for the duration. This attack will target the Tank, who should move out of the area to avoid taking continuous damage.

Delay-action Charge

AoE Markers

Targets two players with AoE markers. Affected players should spread out from the rest of the group to avoid unnecessary damage.

Gunsaw

AoE

Grynewaht will move to the center of the arena before targeting a random player. Then, he will begin to continuously fire at them in a straight line. Move out of the line of fire of other players while the Healer prepares to recover the targeted player's health.

Prey - Thermobaric Charge

Proximity AoE

Targets a random player with a proximity marker. The affected player should move as far away from the rest of the party to drop the marker, then quickly run back to reduce the amount of damage taken.

Sawblades

AoE

Giant saws will spawn around the arena and cast a large line AoE. Find the gap between the AoEs and stay there to avoid this attack. This attack usually occurs at the same time as Gunsaw.

Magitek Bits - Chain Mine

AoE/Knockback

Similar to the Magitek Bits from Magitek Hexadrone, Bits will spawn around the arena that will use line AoEs that knock back players that move into them. This will make dodging the rest of Grynewaht's attacks more difficult, as it will reduce the safe area of the arena.
