You will create new Remix characters (Timerunners) for this event on whichever realms you choose. So that can be the realm on which you mainly play, and it can be realms where you have some alts, and it can be a realm that’s completely new to you.
When you select a Timerunner and hit ‘Enter World’, you’ll enter the Remix world and play there starting at level 10. After the event ends, your Timerunners will be converted into standard characters and you’ll have them available to you in the character selection screen alongside your other characters.
When you’re in Pandaria on a Timerunner, areas that changed during original Mists of Pandaria or later (such as the Vale of Eternal Blossoms) will look like they do in Chromie Time. So the Vale won’t have its original look, nor will it have its Visions of N’Zoth look/content.
The original legendary cloak questline will not be available. You’ll want to reach level 70 on a Timerunner and receive the legendary cloak appearances on your Cloak of Infinite Potential to enable access to Ordos for this event as well as the rest of your WoW account.
Items that were only available during the original release of Mists of Pandaria will not be available in this event. This includes the Kor’kron War Wolf, challenge mode sets, and heirlooms. On the other hand, Rare drops that are available in Dragonflight today, such as the Son of Galleon or the Astral Cloud Serpent, will drop in Remix and can be purchased by Remix characters using the Bronze currency.
This event includes all of the races and classes that are available in Dragonflight. Keep in mind that there is a one-Evoker-per-realm limit in Dragonflight that some players will want to plan around.
We aren’t planning to make changes to content that is available to Dragonflight characters today.
What will be completely different for Timerunners is Remix-specific loot. With some exceptions, every source of loot will drop everything that can be obtained in Remix, and the harder-to-kill enemies will have a higher chance to drop better loot. The exceptions will mostly be zone-based appearances. For example, Remix loot that drops in Throne of Thunder will have the look of ToT raid gear, and outdoor world loot will not.
