Method Boss Review
This fight has some interesting mechanics and lasts a while. Players will have to fight through three unique phases, and essentially each could be their own “classic” boss fight. The final phase also brings out a slight DPS check, pushing players to want to max out their potential. Overall, a huge step up in terms of meaningful mechanics from some of the earlier encounters.

Strategy
Reliquary of Souls has 3 phases, each with their own strategy. Phase 1 is rotating Fixate throughout your tanks to keep them alive during each fixate while dispelling Soul Drain.
Phase 2 is all about interrupting every single cast the boss does and spell stealing his Rune Shield.
Phase 3 is all about burning the boss down fast before his ramping shadow damage is too much for the raid to handle. Do not worry about mana management, as there are intermission phases between phases, where killing ghosts that spawn will replenish your mana and health.

Phase 1: Suffering
Have 3 tanks ready to alternate who’s closest to take the next Fixate. No healing happens in this phase so all healers need to help contribute DPS during this phase. During Enrage, tanks need to use all defensive cooldowns available or have a Rogue tank it with Evasion.
Three things to get right here:
- Tanks alternate every Fixate
- Survive Enrage.
- Dispel Soul Drain ASAP
Your tanks will want as much Avoidance and Stamina as possible for this phase, as they must survive the entire phase without any heals. 2-3 tanks should alternate every 5 seconds for Fixate, and when Enrage happens, they should pop any avoidance trinkets like Moroes' Lucky Pocket Watch or Badge Of Tenacity
Priests can and should use Power Word: Shield on tanks to absorb some damage, as thats the only "heal" that can be used here.
Phase 2: Desire
The damage reflected really isn’t noticeable, so mainly focus on getting all interrupts down on the boss. Set up a rotation to ensure every kick is accounted for. All spells are on predictable timers, so nothing should be coming out of nowhere here.
Three things to get right here:
- Interrupt all Spirit Shock casts.
- Interrupt all Deaden casts.
- Mages need to spell steal all Rune Shield casts ASAP.
A Warlock should apply Curse of Tongues to the boss to allow for more reaction time to kick the boss's casts. Rune Shield needs to be spell-stolen ASAP, as the boss will cast one of his 2 spells after. If the boss gets Deaden off, and then gets Spirit Shock off after, it will one-shot your tank.
Phase 3: Anger
Raid-wide shadow damage will be going out throughout the phase, increasing over time, eventually killing everyone.
Three things to get right here:
- Do not take threat off the tank to prevent Seethe.
- Heal those hit with Spite, and make sure they are at high HP before Spite goes off.
- Use all damage cooldowns, including Bloodlust on this phase to beat the DPS check.
A "safe" strategy you can do is to have your off-tank get initial aggro on the boss, then your main tank taunt off to gain the 200% threat buff, while your DPS wait for the main tank to build threat at double the rate. After 3-6 seconds, the rest of the raid can then start dealing damage.
Players hit with Spite will need to make sure they are close to full HP before the damage goes out, as they are also taking ticking shadow damage that could kill them right after the cast is finished. Besides that, this is just a DPS check, burn the boss before the ramping shadow damage becomes unhealable and it's GG!
