First introduced in Patch 10.1, Dragonflight Season 2 Master was awarded to players who cleared Heroic Aberrus, gained the rank of Challenger II in rated PvP, or earned the Keystone Master achievement during Season 2, allowing three avenues to receive the Draconic Mark of Mastery, which could then be turned in for a single free Heroic-level tier piece.
After it was announced that the revival catalyst would be available from the beginning of the Season, it was unclear if the Mark of Mastery would be returning, but it appears that players will be able to benefit from both – potentially allowing at least a 2-piece tier bonus to be gained very early in the Season without looting any boss drops whatsoever, especially when combined with the Omni-Token!
