Scarlet Enclave in Season of Discovery is a weekly lockout (resets Tuesday). It’s tuned for 20 players, but accepts up to 40 players. Loot does not change based on player count, which means the more players you bring, the easier it is to kill each boss, but the less loot each player will receive on average.
There is only one preset difficulty level for Scarlet Enclave.
Enter the raid using the cave instance portal above the Scarlet Base Camp in southeast Eastern Plaguelands, west of the entrance to Tyr’s Hand.
Boss names will not be spoiled in navigation, but full names and mechanics are spoiled in actual boss guides. Other lore will not be spoiled.
