Riftbound: Radiance Summoner Skirmish window opens November 9

Starting Monday, November 9, 2026, the first Summoner Skirmish window for Radiance opens. The official roadmap calls that out explicitly; the second window opens on December 14 (Riot roadmap, retrieved 07 Nov 2026).

Windows and format

Per the UVS Radiance Dates and Details document (UVS PDF, retrieved 07 Nov 2026):

• Summoner Skirmish I: November 9 through December 13, 2026
• Summoner Skirmish II: December 14, 2026 through January 17, 2027
• Format: 1v1 Constructed, best of 3, Swiss rounds with optional top cut, Competitive Organized Play
• Stores may host one Skirmish in each window

The same source lists a kit with participation, top-cut, and champion promos plus a champion playmat (while supplies last). Any extra store credit or booster prizes are set by the individual store and should be checked on that event’s listing.

Where to find events

Official events run through the Riftbound Gaming Network. Search by location and date in the event locator or on Play Riftbound. Listings already exist in Germany and elsewhere for early November dates and later in the month. Always confirm start time, entry fee, and capacity on the specific listing and with the store.

Radiance has been legal in Standard since its October 23, 2026 release (per the roadmap and UVS document). If you still need cards for a constructed list, check what you are missing before the local date.

Next step

Find a Riftbound store near you in the TCG Date store directory and check there or in the event locator whether a Summoner Skirmish is scheduled.
