The Reins of the Obsidian Krolusk is a mount item in World of Warcraft. When used, it teaches the player how to summon an Obsidian Krolusk — a dark, reptilian/bug-like mount in the “krolusk” family.
This mount is bound to your character when picked up (i.e. “Binds when picked up”) and is classified as “Unique.” requires you to be at least level 50 (or higher, depending on expansions/riding skill) to use it, and you need at least “Apprentice Riding” to be able to ride ground mounts.
Visually, it’s a striking, obsidian-colored mount, reflecting its name. It’s part of the krolusk mount family (which includes several variants) used for ground travel.
This mount isn’t something you buy from a vendor or get by farming a regular drop — it is earned as a reward from a meta achievement in the Battle for Azeroth expansion.
The mount is awarded as part of the “Glory of the Wartorn Hero” meta-achievement.
To complete Glory of the Wartorn Hero, you have to finish a series of sub-achievements tied to 10 Battle for Azeroth dungeons at Mythic difficulty, along with a total of 27 specific achievements (various challenges, boss mechanics, etc.).
Once the meta achievement is completed, you receive the mount as the reward.
In practice that means you need to run all ten BfA mythic dungeons, complete multiple boss and dungeon challenge achievements, and satisfy all criteria required by the meta.
Because it’s tied to a “glory/meta” achievement, this mount is viewed as a prestige reward — you show that you’ve mastered many dungeon challenges to get it.
Difficulty & time investment: Completing all 27 specific achievements across 10 mythic dungeons is nontrivial — it often requires coordination, knowledge of boss mechanics, and optimized dungeon runs.
Group or carry might help: Many players use carry or boosting services (with skilled players) to guarantee completion of the more difficult sub-achievements.
Watch for updates or expansions: As WoW evolves, Blizzard might change requirements, scale, or even make the mount easier/harder with patches. Always check the current meta.
Check that your character meets riding & level requirements (especially if you're playing on a fresh or legacy account) before attempting. safety:
