The final raid season starts on 3rd August 2022 and, instead of a new raid, it will be a "refresh" of the previous three raids.
On a rotating basis, each of the raids will become "Fated", gaining a Mythic+ type affix to increase difficulty levels and dropping higher level gear as a result. Each raid will be "Fated" for a week, before moving onto the next raid. Any raids that are not "Fated" that week, will remain as they have always been.
When a raid is "Fated", it will be fated for all difficulty levels and should be as follows:
LFR will drop Item Level 265 gear for the majority of the bosses, rising to 272 for the later ones. It appears there is a 240+ ilevel entry.
Normal will drop Item Level 278 gear for the majority of the bosses, rising to 285 for the later ones, with a 265+ ilevel entry requirement.
Heroic will drop Item Level 291 gear for the majority of the bosses, rising to 297 for the later ones, with a 278+ ilevel entry requirement.
Mythic will drop Item Level 304 gear for the majority of the bosses, rising to 311 for the later ones, with a 291+ ilevel entry requirement.
At some point prior to the start of the new expansion, the "rotation" of raids will stop, with all three previous raids remaining "Fated".
The affixes work on a per boss basis, with each boss having one of the affixes applied. The affixes remain static during any one week (the same boss will always have the same affix, during that week, on any difficulty level), however, they change each week. So for example the first boss in Castle Nathria on one week will not necessarily have the same affix in a different week.
Summons a Chaotic Essence which casts Chaotic Destruction, inflicting 799 Cosmic damage to all players if successful.
Upon interaction, the essence becomes hostile and instead continuously manifests Chaotic Motes. These motes channel 3 Cosmic damage into targeted players every 0.5 sec. for 3 sec. When defeated each mote splits into additional motes.
After 15 sec the Chaotic Essence dissipates, granting all players 2% increased damage done, 2% increased healing done, and 2% absorbs done for 25 sec. This effect stacks for each Chaotic Mote slain.
Note - This affix doesn't seem too difficult and adds a little extra raid damage. Interact with the Essence to make it summon motes, kill the motes to get a bigger damage buff at the end of the effect!
Charges a player, inflicting 3 Cosmic damage every 1 sec. for 30 sec. This effect stacks.
Upon removal this charge jettisons Creation Sparks to nearby locations, infusing players within 0 yards of the impact location, increasing the flow of time by 15%, increasing casting, attack speed, cooldown recharge rate, and periodic tick rates and additionally increasing movement speed by 45% for 20 sec. This effect stacks.
If a Creation Spark impacts the ground with no player present to infuse the Creation Spark explodes, inflicting 10 Cosmic damage every 2 sec for 20 sec. This effect stacks.
Note - This affix seems like it's the most coordination intensive. Random players will be given a Creation Spark debuff which can be dispelled. When dispelled or timed out, multiple soaks will be throw out around the player. Catching it will give you a massive buff! Missing a soak will deal raid wide damage.
Empowers the caster, inflicting 1 Cosmic damage to all players every 3 sec.
Upon removal this barrier manifests as one attackable enemy, casting a shared 400 absorb shield with all other enemies for 15 sec. A second unit manifests that also can be healed to reduce the shared shield.
Upon expiration the barrier explodes, inflicting 50 Cosmic damage and an additional 5 Cosmic damage every 1 sec. to all players for 8 sec.
If broken this effect backfires, inflicting all damage done to each enemy during the barrier as Cosmic damage, and additionally grants all players up to 25% increased damage done, 25% healing done, and 25% increased absorbs done for 40 sec.
Note - This affix seems pretty straightforward: Break the absorb shield by dealing damage to all enemy targets before it expires. Healers can contribute by healing the new NPC!
Manifests an attackable enemy which continuously casts. This enemy remains immune to damage until the first successful cast or interrupt. Successful casts inflict 30 Cosmic damage to all players. Every 5 sec. the emitter gains 0% increased damage done. This effect stacks.
When successfully interrupted the emitter radiates, inflicting 5 Cosmic damage to all players.
Upon defeat this enemy infuses all players with power based on the energy level of the emitter, increasing mastery by up to 10, critical strike chance by up to 10%, versatility by up to 10%, and avoidance by up to 8.
Note - As long as you have a Death Knight, this affix seems easy. interrupt the add once to make it attackable, have your Death Knight grip the add in and kill it, interrupting anymore casts. Players can opt to leave the emitter alive for longer, but it will deal more damage but give you a bigger buff when you do kill it!
In Season 4, when a raid is Fated for that week, its corresponding World Boss will also be Fated:
