Blizzard has posted the Patch Notes for Version 3.4.2 Wrath of the Lich King Classic, which includes the Phase 3 Update that just went live on Classic realms.
Wrath Classic Patch Notes Version 3.4.2June 20, 2023New Raid: Trial of the Crusader and Trial of the Grand CrusaderThis content becomes available on Thursday, June 22 at 3:00 p.m. PDT.Challenge the five boss encounters in the Trial of the Crusader and Trial of the Grand Crusader 10 and 25-player raids on Normal and Heroic difficulty. Trial of the Crusader (Normal difficulty) shares a lockout with Trial of the Grand Crusader (Heroic difficulty), but you may dynamically swap from Normal to Heroic and back again within the same raid size. For example, if your raid group clears the raid up through Faction Champions on Heroic difficulty, you may swap to Normal difficulty and complete the instance on Normal.
You may also do this difficulty swapping on a per-boss basis. Using the example above, you may clear up through Faction Champions on Heroic, then swap to Normal for the Twin Valkyr encounter, and then swap back to Heroic for the Anub’arak encounter. Please note that to be eligible for Tribute to Insanity and the additional tribute chest and rewards, you must do the entire Trial of the Grand Crusader raid on Heroic difficulty in that same lockout.
10-player and 25-player versions of the raid are still separate lockouts and do not impact one another at all. The requirement to have cleared Trial of the Crusader before attempting Trial of the Grand Crusader has been removed. Adjustments have been made to the acquisition rate of both Emblems of Triumph and Trophy of the Crusade in Trial of the Crusader and Trial of the Grand Crusader:1 additional Trophy of the Crusade.
