If you enjoyed solving Nurseries in Sumeru of Genshin Impact, finding Unearthly Marvel Treasures in Honkai: Star Rail will be a delight. These exploration puzzles involve stepping on a maze of tiles, where you can only step on each tile once. Awaiting you at the end of these holographic mazes are Bountiful Treasures to reward you for your effort. You’ll unlock the Unearthly Marvel Achievement if you discover every Honkai: Star Rail Unearthly Marvel Treasure. The Stellar Jade ×5 for this Achievement is decent. Conversely, the bountiful rewards from the puzzles’ Bountiful Treasures are well worth it.

Completion of “Sensitive Beings I, II, III” Adventure Missions and their corresponding Unearthly Marvel puzzles will reward you with three Bountiful Treasures. Clear the quest chain and find the previous four Treasures via exploration to unlock the Unearthly Marvel Achievement.
