Riftbound 'Radiance' Released on the 23rd: 9 Legends and 3 New Keywords Rules Confirmed
Deploy, Disarm, and Show Off rules applied from the 16th; Korean edition falls within 2027 release window

Riot Games' League of Legends trading card game, Riftbound, released its fifth set, 'Radiance', on the 23rd. The official website playriftbound.com stated in an announcement on the 12th that Radiance would launch worldwide on October 23, and the release date remained unchanged from the schedule first revealed in August.
According to a press release issued by Riot on August 4, Radiance is the final set of 2026 themed around musical performances. The set features 180 cards, of which 66 are showcase cards.
9 Legends and Product Lineup
According to the official Pre-Rift guide, 9 new legends are added in this set.
| Category | Details | |---|---| | New Legends | Ekko, Evelynn, Jarvan IV, K'Sante, Mordekaiser, Orianna, Riven, Seraphine, Ziggs | | Showdown Decks | Seraphine, Evelynn (2 types) | | Vault | 6 booster packs, foil tokens, 36 runes, storage box | | Pre-Rift Kit | 5 booster packs, 1 legend-themed champion pack, Heimerdinger promo |
The champion pack contains 1 legend, a rare champion, a battlefield card, and support cards. The pre-release event, Pre-Rift, was held in a sealed format with store-specific schedules from October 16 to October 22. The main deck requires a minimum of 25 cards, and opened cards can be used beyond the normal limit (3 cards). The 'Heimerdinger, Academy Instructor' promo given to participants cannot be placed in the sealed deck.
An introductory article published on ICv2 reported that all 9 legends feature over-number variants and artist-signed editions, with a second ultimate rare appearing at a rate of approximately 0.025% in booster packs. The Summoner Skirmish event periods begin on November 9 and December 14. Product prices were not confirmed from official sources.
3 New Keywords, Rules Effective from the 16th
Riot released the 'Core Rules: Radiance Patch Notes' on the 9th, and the rules took effect starting on the 16th. There are three new keywords.
- Deploy: A keyword attached to equipment. Equipment can be placed on any battlefield regardless of whether an enemy has claimed it, and if the opponent controls that battlefield, the equipment is destroyed.
- Disarm: The first time a unit attacks in each combat, it lowers the Might of 1 enemy unit on the same battlefield by 1 for that turn. Disarm 2 is -2, and multiple effects stack.
- Show Off: Reveals cards from the hand meeting certain conditions or selects friendly objects on the field to trigger additional effects. The information of the revealed card is locked in at the moment it is revealed.
The patch notes also included the establishment of a dedicated layer for copy effects and revisions to the 2v2 scoring rules. Riot announced a rewrite of the rule documents for the 'Legacy' milestone in January of next year, stating that the mechanics will not change.
What Changes for Korean Readers
This Radiance set is not in Korean. The Korean edition of Riftbound was launched with the first set, 'Origin', on September 18. Official Korean announcements stated that the second set, 'Spiritforged', will be released in December, followed by 7 sets from the third set, 'Unleashed', through the 9th set in 2027. Although Radiance, the fifth set, falls within this scope, the release timing for the Korean edition is not mentioned in the notice. Riot stated its goal to release the Korean edition on the same day as the global version starting with the 10th set in early 2028. It has not been confirmed whether domestic distributors will officially sell the overseas version of Radiance in Korea.
