Uldir – Mythrax the Unraveler Guide

Mythrax the Unraveler

Switches between two phases at 66% and 33% health. Main mechanic of the fight is Annihilation debuff which stacks, and each stack reduces max health by 1%. For each x stacks a white ball (Essence Fragment) will spawn nearby and going over it will reduce x stacks. Note that anybody can pick these up, and it works as a kind of soft enrage. At 20% boss health Essence Fragments will no longer spawn at all, use BL/TW and potions at this point, because tanks will die eventually when balls no longer spawn.

Phase 1

Tank gets slapped with Essence Shear front cone attack. This will prevent generating any Essence Fragments, and after swap the tank needs to run around picking fragments other people in the raid left behind.

Oblivion Sphere charms all players nearby, for this reason raid needs to be well spreda out so that as few people as possible get hit by these. While charmed you get damage and Annihilation stacks (and Essence Fragments). Doing damage to the characters or using knockbacks/grips will get them off the charms. Also when players are freed from the spheres they’ll do aoe burst on whole raid so make sure not do free all three at the same time when raid is at low health.

Imminent Ruin is a dot on 2 targets for 12 seconds applying increasing slow debuff. When the debuff expires everyone gets shadow damage based on proximity, and Annihilation stacks within 12 yards. Two debuffed people must run to opposite ends of the room, kinda like soulbursts on Argus.

Obliteration Blast is targeted towards random player, and everybody hit by it gets shadow damage and Annihilation stacks. Avoiding it is good idea in general, but eating these on purpose might be necessary to get enough Essence Fragments for tanks.

Phase 2 – 60 seconds to kill adds before boss gets active again to avoid problems (like Kin’garoth)

Boss moves to middle of the room and gets 99% damage reduction shield that knocks people back, just like Aggramar during add phases, then spawns two Oblivion Spheres from first phase. Also everybody in raid gets 10 stacks of oblivion and soem damage. Spread out before phase change because Oblivion Spheres happen at the same time, but after orbs are handled it’s safe to stack back up for aoe healing.

Obliteration Beam is new ability that works and looks like the beam Gul’dan spams in first phase. Big green thing where people need to move out from. As expected, it will stack Annihilation really fast on anybody who gets hit by it. This beam might be targeted towards player closest to boss so it might be possible to bait it.

Visions of Madness adds that are shadowy copies of players spawn on a number of players (2-5 depending on raid size) that spam Mind Flay. It does pretty high damage and can be interrupted. Stunning and nuking these down asap is a priority.

Two big N’raqi Destroyer adds spawn on both sides of the boss. These need to be tanked at least 40 yards apart from each other and they cast interruptible Void Volley that does damage to everybody in raid. They also do Essence Shear on tanks so they must be tanked towards walls.
