Keystone Myth returns for Midnight Season 2
The first public build of patch 12.1.5 has added the Season 2 entry in the Keystone Myth achievement series, and it works exactly the way the Season 1 version did.
What it rewards
Midnight Keystone Myth: Season 2 asks for a high Mythic+ rating earned during Season 2. It pays a title and a saddle that Lindormi in the new Silvermoon will trade for a mount of your choice.
The mount selection has not been refreshed. It is the same list that was on offer in Season 1, so anyone who already picked one knows exactly what is available.
How much rating you will need
The achievement description does not state a figure yet. Season 1 required 3,400, so that is the sensible planning number, though a slightly higher bar would not be a surprise given how players performed last season.
Getting the rating
3,400 is roughly the level where a solid pool of keys has to go clean rather than just get timed, and it is the point most players stall at. If your rating is short and the season is not, a Mythic+ rating boost closes the gap before the achievement locks with the season.
