50: The S-Class Holy Spirit Priest

"The Secret of Ascension? This dungeon... if I recall correctly, SSR Club was the first to clear and unlock it." 

In Infinite Dimensions, once a player completed a hidden quest, the corresponding dungeon could become available to others with reduced difficulty to encourage exploration. 

Orson had vivid memories of The Secret of Ascension, a legendary-tier dungeon. If he hadn't completed the Missing Barrier Stone quest first, SSR Club would likely have claimed the first legendary dungeon clear instead. 

"Did you give this questline to anyone else?" Orson questioned Veijander sharply. 

The dwarf blacksmith hesitated, looking a bit guilty. "Kid, I've got a keen eye for talent. You'll definitely pull this off!" 

As expected, Veijander's quest-giving "easter egg" wasn't a secret solely to Orson. SSR Club clearly knew about it too. Judging by Veijander's reaction, SSR must have submitted high-quality materials to unlock the questline.
