SoD raid in season 4 is again relevant. This is one of the three returned Shadowlands raids, but with increased difficulty and higher loot.
Instead of a new seasonal raid, weekly Fated Affixes have been added, similar to Mythic+ dungeons,
which add new mechanics to raid bosses.
Loot level has increased and depending on the difficulty of Fated Raids you can get 278-311 iLvl gear,
but as before you can get mounts from the Nine and Mythic Sylvanas
Seasonal rewards for Fated Raids include:
new Feat of Strength achievements, Jigglesworth Sr. mount, the "Hero of Fate" title and Shadowlands Raid Teleports.
You can change it later in the top nav menu. Please note, that price of services might be different for different regions.
Also the currency matches certain region.
