Shriekwing

The tactics here are concerned with mythic difficulty. Please note that these are based on our ongoing raiding, and these will be updated as we progress.

Before the fight

As with all fights:

• check the dungeon journal
• check tactic videos, such as on FatBoss
• read up on tactics, such as at the Wowhead guide

Shriekwing is a two phase encounter which requires players to utilize line of sight and visiblity mechanics. The first phase has the raid fighting the boss head on, while Phase 2 has the entire raid hiding from the boss at all times while dodging her invisible sonic rings. These phases are timed, and repeat until the boss is killed.

A single target spec is required. There is a fair amount of movement during the fight with burst speed buffs and abilities being particularly useful.

Phase 1 | 0 - 110 seconds/100% energy

There are 6 main mechanics for the entire raid to be aware of:

• wave of blood applies a DOT on all players
• the blood lantern is available which can be picked up and applies the bloodlight debuff, allowing players to see sonic rings from echoing-screech (and echoing sonar in phase 2)
• earsplitting shriek that spawns sanguine ichor under every player
• echolocation which triggers descent that also spawns sanguine ichor
• echoing-screech which targets a random raid member. Note that in mythic the generated sonic rings are invisible unless affected by bloodlight.
• blind swipe which targets a random raid member

Tanks also will be affected by:

• exsanguinating bite

Phase 2 | 100 - 0% energy

At the start of the phase:

• The boss gains blood shroud and anyone within 12 yard will be one-shot by murder prey
• The boss channels echoing sonar

Note that the following still occur:

• echoing-screech

General Approach

• There are 4 pillars in the room which block line of sight
• Use these pillars to break line of site for echoing-screech as unnessecary sanguine ichor is often very bad
• There is a DPS requirement, with a 1 - 2 - 1 - 2 - 1 being the enrage timer; thus there are three DPS phases possible in total
• Timewarp/heroism should be cast on pull.

Approach: Phase 1

This phase is a case of controlling the position and mechanics of the boss to set up safe spaces for the raid. The positioning requirements are very precise and some are raid wiping.

To optimise DPS, the raid will need to be rotated. Familiarise yourself with the following layout ideas:

• Divide the room into two, the near side (close to the raid entrance) and far side
• Start at the far side of the room, initially using the far left pillar
• After the first phase 2, completely switch sides to the near right pillar

The raid layout is designed to mitigate visibility requirements for echoing-screech and is as follows:

• Position Shriekwing to be close to the far left pillar. This needs to be accurate. Purple and orange both should have a line of sight to shriekwing. Yellow must be out of line of sight. Orange must be within melee range.
• Tanks should face Shriekwing toward the wall, with the remaining players all stacked in a line up to purple. A precise alignment is required in order to bait mechanics.
• blind swipe can be avoided by sidestepping the mechanic; it does not track players. Be sure to reset position afterwards as the bait happens shortly after this cast.
• To mitigate echolocation run to a safe part of the floor and proc descent dropping the sanguine ichor there. There are two safe locations as follows:
  • For most of the phase, this should be place at the wall closest to the boss: for example, near the stairs
  • During echoing-screech this should be behind the left hand skull

Precise movement allows the visibility mechanics of echoing-screech to be ignored. These movements are as follows:

• If the raid is correctly aligned between Shriekwing and purple, then he will cast echoing-screech into the raid. This is a 3 second cast, after which the boss channels echoing sonar.
• This echoing sonar will be invisible, but its location is fairly predicable if the boss is aligned correctly
• Use a speed boost, such as stampeding roar to quickly move the DPS and healers to orange, where they continue attacking the boss. Please note that this location is extremely sensitive and you should stack at a maximum melee range.
• As mentioned above, place the sanguine ichor from echolocation behind the skull
• The sonar will despawn just as earsplitting shriek is cast
• Once the earsplitting shriek cast has begun, the ranged should break line of sight at the orange marker pillar. The raid should quickly reset position to purple afterwards.

There will likely be three rotations of phase 1. As per the diagram, the raid can swap between the top left pillar and the bottom right pillar. A combination of the movement of the boss in phase 2 and unintended sanguine ichor can cause this. Please be aware of the raid leader's call on where to stand.

Note that during the transition from Phase 1 to Phase 2 the boss still takes damage. Ranged players can continue to damage the boss, but it is vital that melee players do not.

Tanks should

• Mitigate exsanguinating bite with a cooldown, and it should be immediately followed by a tankswap or a Kyrian special ability

Healers should:

• Rotate a cooldown for the wave of blood to ensure that players are topped off before the movement to the pillar

Key mechanics to master:

• Precise movement to the correct markers (purple -> spread -> purple -> orange -> yellow)
• Run out of the group if echolocation is cast on you, returning quickly after it is complete

Phase 2 | 100 - 0% energy

In this phase, you must avoid the boss' mechanics. DPS is heavily reduced throughout, so this phase is survival only. Do not attempt to DPS the boss.

To complete this phase:

• Have a raid player pick up the the blood lantern and apply the minimum stacks of bloodlight possible on the raid
• Drop the blood lantern immediately after this, but ensure that it is easy to pick up again
• Before stacks drop off, reapply bloodlight. Be aware that extra stacks are substantially less of an issue than losing sight of the echoing sonar
• The raid must avoid all sonic effects
• Stack at red and simply move round this pillar as the boss moves around the room. Be careful as it is possible to touch blood shroud through the pillar
• When echoing-screech is cast ensure you are out of line of sight

This phase will end when the boss has 0% energy remaining.

TL;DR

Come on... It's mythic. Read the full thing please.

Phase 1:

• Move out to the wall for echolocation / descent to drop sanguine ichor away
• Avoid the swipe/aoe mechanics (blind swipe / echoing-screech)
• Ensure you stick tight to the correct raid marker (purple -> spread -> purple -> orange -> yellow)
• Break line of sight for echoing-screech

Phase 2:

• Don't stand in blood shroud
• Avoid the echoing sonar
• Break line of sight for echoing-screech
