Vendetta Legends and rivalries

Riot describes the set as "clashes between former friends, immortal enemies, and members of the same family". Its nine new Legends come in rival pairs from enemy colours, such as Shen and Zed, and Mel and Ambessa. [1]

Each new Legend also has an Overnumbered version with an artist's signature, and 22 champion Overnumbers show rival pairs as two-card artworks. Riot states that rarity rates are averages across the print run, not guarantees for any pack or box. [1]

Vendetta mechanics: Flow, Burn and Empower

Flow appears on spells. If you pay a spell's Flow cost, you can play it from your trash instead of your hand. The spell is then banished, so you get one extra use. [1] [3]

Burn moves cards from the top of a Main Deck into the trash. Some cards trigger when cards are burned. Burning can put Flow cards in your trash, but it also brings you closer to running out of cards. [1] [3]

Empower lets units, gear and legends gain new abilities after they enter play, often after you pay a cost. An Empowered card keeps that status until it leaves the board or is disempowered. [1] [3]

Vendetta also adds Unit-Gear, a card type that counts as both a unit and a gear, and Decrees, a cycle of spells, one for each domain, that strike cards of the opposite domain colour. [1]

These summaries are a starting point. Check the official Vendetta rules update for detailed interactions with older cards. [3]

Which Vendetta product should you start with?

New to Riftbound? The Zed vs Shen Showdown Decks give two complete decks, so you and a friend can learn the game together without building from boosters first.

Enjoy recursion and long games? Flow and Burn work together: Burn fills the trash, and Flow lets you play spells from it. A booster box gives you the widest choice of these cards.
