Riftbound Radiance, releasing worldwide October 23, 2026, brings two collector-focused details worth understanding well before opening a single pack: a new Ultimate Rare chase card and a returning Vault Bundle product.
Neither is a small footnote. The Ultimate Rare is only the second one Riftbound has ever produced, and the Vault Bundle is a distinct sealed product with its own specific contents rather than a repackaged booster box.
Both come with real, official numbers behind them, which is worth knowing before assuming either one works the way an equivalent product does in another trading card game.
Here's exactly what's confirmed about Radiance's Ultimate Rare and Vault Bundle.
Riftbound's first Ultimate Rare, nicknamed the Baron, came from Unleashed, Set 3. Riot has said openly that while finding one was exciting, it wasn't quite as rare as intended, and Radiance's Ultimate Rare is built to be significantly harder to find than the Baron.
The card itself hadn't been revealed as of late September, with Riot's own preview schedule pointing to an October reveal closer to release.
Riot has published a specific number for this card's rarity: an Ultimate Rare appears in approximately 0.025% of booster packs on average across the entire Radiance print run. There's no guaranteed Ultimate Rare in any single pack, box, or case, and pack contents are randomized during manufacturing.
That figure makes it dramatically rarer than a standard Rare or Epic slot, and collectors should treat any stated appearance rate as an average across the full print run rather than a promise for any individual purchase.
Each Radiance booster pack contains seven Commons, three Uncommons, one foil slot that can be a Common through Epic, one guaranteed Rare or Epic, and one additional slot that can land on a Rare, Epic, Alt Art, Special Alt, Overnumber, or the Ultimate Rare itself.
A final slot holds a Token, Rune, or Alt Art Rune, rounding out the fifteen-card pack structure. The Ultimate Rare only ever comes from that one flexible slot, never a guaranteed position.
The Vault returns for Radiance as a distinct sealed product, including a storage box, six Radiance booster packs, foil tokens, and a full set of 36 Runes. That combination makes it a genuinely different purchase from a straight booster box rather than just a themed repackaging.
The included storage box alone is worth factoring into the Vault Bundle's value, since it gives a dedicated home for the cards pulled from its six packs plus whatever else a collector is already storing.
A full set of 36 Runes in one product is a meaningful shortcut for anyone trying to complete Radiance's Rune collection without opening dozens of individual packs hoping for specific pulls. Runes aren't the headline chase item in most trading card games, but a guaranteed complete set removes a real source of frustration. EVORETRO's Magnetic Card Storage Box is a practical way to keep that guaranteed Rune set alongside the rest of a growing collection.
Combined with six actual booster packs, the Vault Bundle gives both a guaranteed collectible component and genuine pack-opening upside in a single purchase.
With an Ultimate Rare pull rate this low, it's worth going into Radiance packs expecting the set's more common Rare, Epic, and Showcase tiers to be the realistic outcome for most purchases. That's not a discouraging framing — it's simply how a 0.025% pull rate plays out across normal buying volumes.
Budgeting a Radiance purchase around the confirmed booster and Vault Bundle contents, rather than the Ultimate Rare specifically, is the more reliable way to plan a purchase, and it keeps a genuine Ultimate Rare pull feeling like a bonus rather than an expected outcome.
It appears in approximately 0.025% of booster packs on average across the print run.
A storage box, six Radiance booster packs, foil tokens, and a full set of 36 Runes.
No, it's the second; the first was Unleashed's Ultimate Rare, nicknamed the Baron.
Fifteen slots total, including Commons, Uncommons, a foil slot, and the flexible slot that can produce the Ultimate Rare.
Whether it's a guaranteed Rune from the Vault Bundle or a genuine Ultimate Rare pull, both deserve protection the moment they're opened. EVORETRO's One-Touch Magnetic Holder gives a top pull a rigid, display-ready case immediately.
For the rest of a Vault Bundle's contents, having enough long-term storage on hand keeps a growing Radiance collection organized as it builds.
