Season 7 is dated about 6 June 2025
in Steam news,
with PanicNet account linking,
the Bard class,
and Chaos Pillars. Season
8 released 12 September 2025 per Steam news. Together with Season 9 on 3 April 2026 and Season 10 on 21 August 2026,
the gaps sit on the official four-month seasonal cycle from Steam store copy.
Bard remains Steam DLC 3305660, a paid class after Season 10. PanicNet linking from Season 7
is still the account layer for Market,

7
notable line and are not restored as a Season

7
carries PanicNet linking,
Bard,

6 June 2025. Season 8 is the 12 September 2025 Steam news date. Season 9 is 3 April 2026
with Incarnation Tree,
Ether Tree,
Prophet,
PlayStation
5, and Architect of Ruin. Season 10 is 21 August 2026 with Ebontharn.

four free classes,
and market filters. The rail exists so a returning player can see that S

Steam date because that is the sealed notable for that tick. Season
7'
s well keeps PanicNet,

and Chaos Pillars on the
2025-06-06 stamp.
Wormholes are cosmetics
Wormholes are the official seasonal high-push content that awards cosmetic skins,
wings,
and portraits rather than pay-to-win power. Steam store copy states the team never sells gameplay advantages. Treat Wormholes as the seasonal ladder for looks,
not as a second campaign SKU and not as a unique-item vendor.
Season 10's Ebontharn Bundle (DLC 4766880)
sells pirate skins,
cursor skins,
a pirate flag back accessory,
chat emotes,
and an Ebontharn UI theme
—
cosmetics on the same side of the policy as Wormhole rewards. Class DLC still gates some characters; Season
10
reduced that wall for four names and for Act
8. Click Season 9 on the timeline for the dated PS5 sentence; click Season 7 for PanicNet and Bard; click Season 8 for the 12 September 2025
stamp. The live rail always points at Season
10 until the next four-month cycle ships.
