Ritual Sites will have a harder difficulty available in WoW Midnight Patch 12.0.7, with the introduction of Tier 6 Ritual Sites. The best part of this is that Tier 6 Ritual Sites will reward Myth Crests when completed. Considering how quickly you can clear Ritual Sites, once you have a high enough Item Level, this is a great way to farm Myth Crests if you are not Raiding or doing Mythic+.
If you are new to Ritual Sites and want more information on how to unlock them and how they work, you can check out our Ritual Sites Overview Guide.

During PTR testing of Midnight Patch 12.0.7, there also appears to be a new weekly quest which rewards an additional Nebulous Voidcore. The quest can be picked up outside the current Ritual Site once you have unlocked Tier 6.
Unlocking Tier 6 Ritual Sites in Midnight WoW
To unlock Tier 6 Ritual Sites, you just need to complete a Tier 5 Ritual Site. If you have not got up to Tier 5 in the Ritual Sites, you will need to complete each tier to unlock the next until you reach Tier 6.
Tip: If you are struggling with which challenges to add, as you must add four challenges in Tier 5, we recommend activating the Magical Alarm Bells, Tendrils, Tainted Corpses and Manifestations. These 4 challenges should give you the easiest and fastest time clearing your Tier 5.
Easiest Challenges for Tier 6 Ritual Sites
Once you have unlocked Tier 6, you will need to activate a minimum of 5 challenges. We recommend the same four as for Tier 5 (Magical Alarm Bells, Tendrils, Tainted Corpses and Manifestations) and adding the Embers or Patrols for Tier 6. These are the smoothest and fastest combination of challenges that we found for Tier 6 Ritual Sites.

Tier 6 Ritual Site Rewards
Tier 6 Ritual Sites will reward the most amount of Field Accolades and Ritual Spoils; they will be harder than lower tiers, in addition to the mobs having more health and dealing more damage you will also be required to have a minimum of 5 challenges active, so may not be as efficient as farming lower tier ritual sites if you are looking for quick Field Accolades and Ritual Spoils.
One of the main reason you will want to do Tier 6 Ritual Sites in Midnight WoW is for the Myth Crests; you will receive 5 Myth Crests at the end of each Ritual Site.
Tier 6 Ritual Sites are a great way to farm Myth Crests as a solo player, along with having a large amount of rewards you can work towards. If you are looking for more information on Ritual Sites check out our Ritual Site Overview Guide.
