Guide
The Verdant Armoredon mount was earned by completing the achievement Dragonflight Keystone Master in the third season of Dragonflight. This achievement required you to obtain a Mythic+ rating of at least 2000 from November 7th 2023 to April 22nd 2024. This mount is now unobtainable and it is not likely to be obtainable ever again.
Dragonflight Keystone Master was notably easier than Battle for Azeroth and Shadowlands (S1) Keystone Master due to the requirement change. BFA & Shadowlands season 1 required every dungeon timed on both Tyrannical and Fortified at Mythic level 15 or higher. It was later changed to 2000 rating which no longer requires you to complete the dungeons within the time limit or at a specific level. To give an example, I reached 2006 rating with my lowest key being a +5 Fortified DOTI: Murozond’s Rise which would not have been possible before.
Additionally, this season was the last to use the old Mythic+ system. In Dragonflight season 4, the system revamped Heroic, base Mythic and M+ dungeons with increased tuning and rewards. For example, a base Mythic dungeon in season 4 would become the equivalent of a Mythic +10 dungeon in season 3. More info can be found in this news post.
