Season 15 continues the partial-revival format established from Season 11 onwards. As usual, here's the detail on which items in this season existed in previous seasons.
|Season 15 Tier||Rewards||Previous Season||Previous Tier|
|Gold 09 (Note 1)||17: Bed 2||9||Normal 24|
|Gold 16||* Fresh Candy||6||Gold 26|
|Gold 17||Profound Darkness Doll||6||Normal 12|
|Gold 19||Gold Crescent, Gold Crescent B||11||Gold 12 (Note 2)|
|Gold 20||Daybreak Defender, Daybreak Helmet, Daybreak Mask (Note 3)||6||Gold 08|
|Gold 21||Daybreak Warrior, Daybreak Long Hair, Daybreak Hairband, Daybreak Eyepatch (Notes 3 & 4)||6||Gold 18|
|Gold 22||Ancient Plate Parts set||6||Gold 10|
|Gold 23||Rejelan Parts set||6||Gold 30|
This is presumed as the end-of-list picture of "Tier 9" in Seasons 13 and 14 ended up being Gold 09 when the season released.
Was also available from Gold 32 (Over Run) as Group2; Group1 was Long Scarf and Checkered Long Scarf which have not been revived.
These tiers also contain the weapon camo * Exacronov; this is not from a previous season.
Updated post-maintenance: The website does not mention Daybreak Eyepatch, but this is a listing omission. The actual reward includes it, meaning the full reward from Season 6 Gold 18 (seen here) is correctly revived after all.
