Cosmic Battle Chest: Item Guide
- Availability: Obtainable exclusively through the Cosmic Battle Shop and The Pass of a Warrior event.
- Reward Structure: Features a Matryoshka-style (nested) reward mechanic, meaning opening a chest has a chance to grant additional chests.
- Overall Value: While it does not allow players to target specific Enhancement Effects, the overall rewards are generally considered reasonably valuable.
2023 Edition vs. 2026 Edition
- Different Drop Rates: Two distinct versions of the Cosmic Battle Chest exist with different Matryoshka continuation rates. Based on available data, this appears to be an intentional design difference rather than a statistical anomaly.
- Higher Continuation Rate: The version introduced in 2026 appears to have a higher probability of generating additional nested chests than the original 2023 version.
- Identification: If both variants are present, the 2023 Edition appears first in the inventory list.
- Contents: Both editions share the same reward pool; only the drop rates differ.

Cosmic Battle Chest Value Ratio
“Intelligent Skin Stone” most likely should be Skin Stones for all attributes together.Or there should be lines for strength and agility too.
Same for Expected value: 100 Cosmic Battle Chest

English is not my native, but I think agility goes with one “l”. I see two in Unboxing 2,000+ Root boxes, line for Agility Skin Stones.
And I think it should be “strength” without “a” letter and with “th” at the end. Difficult word, took me some time and effort to remember it.

– Boss, it’s “aluminium”, not “alumini”.
– The one’s who is too smart are going to unload tuck with iron!
