Riftbound Vendetta Set Guide: Legends, Mechanics, Release

TL;DR: Vendetta is Riftbound's 4th main set, released worldwide (English and Chinese, same day) on July 31, 2026. It runs 166 cards, including more than 50 Showcase premium cards, and introduced 9 playable Legends, fewer than the 12 each of the two prior sets added. The theme is rivalries: rival Legends like Shen and Zed, and Vi and Jinx, are paired throughout. The current post-ban field is broader than the early Kennen-led snapshot, with Irelia and Master Yi labeled Tier 1 in the October 3 report. Set 5, Radiance, ships October 23, 2026, with two more sets already dated beyond that.

Updated October 5, 2026: Vendetta remains the current card pool before Radiance releases. The current meta references below now use the October 3 post-ban report. Earlier Kennen results and the September 3 price snapshot are labeled as historical rather than current quotes.

What Is the Riftbound Vendetta Set? (Quick Answer)

The Riftbound Vendetta set is the game's 4th main set and its current, tournament-legal card pool, released worldwide on July 31, 2026. It's a 166-card set built around a rivalry theme, introducing 9 new Legends, three new keyword mechanics, and the game's first dedicated two-player Showdown Deck starter product. Every deck guide and tier list this site has published so far draws entirely from Vendetta's card pool.

Riftbound Vendetta Set Overview: Size, Legends, and Release Date

The Riftbound Vendetta set released to a single unified worldwide date rather than staggering regions, a detail that matters more than it sounds. Riot shipped the English and Chinese versions of the set on the exact same day, July 31, 2026, which is part of why the tournament data covered in this site's Riftbound complete guide reflects one global metagame instead of two regions drifting apart on different card pools.

The set itself runs 166 cards total, more than 50 of them Showcase variants, the alternate-art premium versions that carry most of the set's actual collector value. That's a meaningfully large release for a TCG still in its first two years, and it's sized up from what came before it in one specific way: Vendetta trimmed the new-Legend count down to 9, compared to the 12 Legends each of the prior two sets, Origins and Spiritforged, introduced. Three of those 9, Ambessa, Mel, and Akali, are entirely new to the game, appearing as playable champions for the first time.

The full Vendetta Legend list: Akali, Kennen, Zed, Shen, Mel, Jayce, Ambessa, Nasus, and Renekton. Some of those names will already be familiar if you've read this site's coverage of the set. The early Kennen-led snapshot changed after the September 18 bans: the October 3 report labels Irelia and Master Yi Tier 1, while Kennen is Tier 2.

The Rivalry Theme: Showdown Decks and Rival Showcase Art

The Riftbound Vendetta set's identity, more than any single mechanic, is rivalry. Riot built the set around pairing enemy or thematically opposed Legends against each other, and that idea runs through the product line, not just the flavor text.

The clearest example is the set's Showdown Deck, a dedicated two-player starter box built around Shen and Zed specifically, the first product of its kind in Riftbound. Instead of a generic two-deck starter, it's built to put one rivalry directly on the table from the first game. It's a smart onboarding move too: two new players can sit down with a pre-set matchup already chosen for them instead of guessing which of nine new Legends to try first.

The rivalry idea extends into the Showcase card pool as well. Among the more than 50 Showcase variants in the set, several are built as connecting art pairs, pieces that reference or complete each other when placed side by side. Vi and Jinx get this treatment, as do Jayce and Viktor, two League of Legends rivalries with a long history well outside the card game. If you're chasing Showcase pulls specifically, knowing which pairs exist changes how you think about a partial collection versus a complete one.

New Mechanics: Flow, Burn, Empower, and the Unit-Gear Card Type

Vendetta is also a mechanical expansion, not just a new card pool wearing the same rules. Riot introduced several new systems with this set:

1. Flow, Burn, and Empower, three newly named keyword mechanics that didn't exist in Origins or Spiritforged.
2. Unit-Gear, a new card type sitting between the existing Unit and Gear categories.
3. Decrees, a new card subtype.
4. Three new token types: Tentacle, Shadow Clone, and Empowered.

That's a genuinely large mechanical footprint for a fourth set to introduce all at once. What none of these do, exactly, in rules terms, isn't something to guess at here. This guide names each one accurately because they're confirmed to exist in Vendetta's card pool, but a full mechanical breakdown, how Burn actually resolves, what triggers Flow, what an Empowered token does on the stack, needs its own dedicated piece once that rules text is verified card by card rather than summarized secondhand. Treat any explanation of exact mechanical behavior you find elsewhere with the same caution until it's confirmed against Riot's own Comprehensive Rules document.

Kennen's Debut: Chaos and Order Come Together for the First Time

Kennen, Heart of the Tempest is Vendetta's most consequential new Legend, and it's worth more attention than its tournament results alone would suggest. Kennen pairs the Chaos and Order Domains, a two-Domain combination that had never appeared together on a Legend before Vendetta. That pairing gives the deck a stun-and-disruption identity, leaning on control effects from both Domains rather than the raw damage a Fury-heavy build would carry.

Two confirmed Kennen-specific cards worth knowing by name if you're tracking the set: Kennen, Storm of Shuriken and Kennen, Keeper of Balance, separate printed cards rather than just flavor variants of the base Legend. Between the new Domain pairing and Kennen's specific card pool, this is the clearest case in Vendetta of a mechanical debut translating directly into tournament results. The current post-ban report places Kennen in Tier 2 with 10 top cuts from September 25 through October 1, while Irelia and Master Yi carry the Tier 1 label.

Analysis: Why a Smaller Legend Count Signals a Maturing Format

Cutting the new-Legend count from 12 to 9 looks like a minor production detail until you consider what it actually buys Riot. Twelve new Legends every set is a lot to design, balance, and support with cards for simultaneously, and it spreads competitive attention thin across a huge roster where most Legends never see serious tournament play. Nine is still a substantial release, but it's a number that lets each Legend get more individual card support and more design attention, which likely shows up directly in how quickly a set's metagame settles into readable tiers rather than staying chaotic for months.

That restraint shows up again in the set's economics. The September 3 price snapshot used by the companion card-values guide listed most base-rarity Vendetta cards below a dollar, while the premium Showcase and Signature tier carried the collector cost. It listed a Kennen, Heart of the Tempest Signature Showcase print at about $272.70. TCGPlayer was not independently readable during this October 5 audit, so that figure is a dated historical snapshot, not a current quote. If you're building a Kennen deck to play, verify the live print price before buying.

What's Next: The Riftbound Roadmap Through Set 7

Riot hasn't left Vendetta's shelf life to guesswork. Set 5, Radiance, is already confirmed to ship worldwide on October 23, 2026, putting less than three months between Vendetta's release and its successor. Beyond Radiance, Set 6, Legacy, is dated for January 29, 2027, and Set 7, The Reckoning, follows on April 30, 2027.

That's three fully dated sets locked in past the set this guide covers, an unusually long public roadmap this early in a trading card game's life. It matters for two practical reasons. First, it gives Vendetta a known competitive window: expect the current post-ban metagame to keep evolving right up until Radiance changes the card pool in late October. Second, it's a signal for anyone deciding whether to invest in singles or sealed product now, a publisher committing three sets and roughly nine months of scheduling in advance isn't treating this as a short-lived side project.
