What "pull rate" actually means for Riftbound
A Riftbound booster contains 14 cards. Each card slot has its own rarity distribution — some slots are locked to a specific rarity floor, others roll on a rarity table. When we say "Legendary pull rate: 1 in 24 packs," we mean: averaged across many boxes, one in every 24 packs contains at least one Legendary rarity card. That's not the same as "you will pull a Legendary every 24 packs" — variance is huge on small samples.
Origins (released Oct 31, 2025)
Riftbound's launch set — the community sample is the largest here, so these estimates are the most reliable.
- Rare: ~1 per pack (dedicated Rare-or-better slot).
- Epic: ~1 in 3–4 packs.
- Legendary: ~1 in 24 packs (roughly one per booster box).
- Chase alt-arts (numbered parallels): ~1 in 72 packs (roughly one per three boxes).
Spiritforged (released Feb 13, 2026)
221-card set with 12 Legends. Community data suggests Spiritforged followed the Origins base rates closely but slightly compressed the alt-art hit rate to compensate for the larger Legend pool.
- Rare: ~1 per pack.
- Epic: ~1 in 3 packs.
- Legendary: ~1 in 24 packs.
- Numbered chase parallels: ~1 in 96 packs. Spread across 12 Legends means hitting a specific chase is roughly 1 in 1,150 packs.
Unleashed (released May 8, 2026)
Unleashed introduced Ambush, XP, and Hunt mechanics, and shipped Champion Legends (Master Yi, Diana, Vi, Pyke, Kha'Zix). It also introduced the game's Ultimate Rare slot — Baron Nashor.
- Rare: ~1 per pack.
- Epic: ~1 in 3 packs.
- Legendary: ~1 in 24 packs.
- Champion Legend (subset of Legendary): ~1 in 60 packs.
- Ultimate Rare (Baron Nashor): case-hit territory — roughly 1 per case of six boxes, i.e. ~1 in 144 packs.
What these mean per booster box
A standard sealed booster box holds 24 packs. Expected value per box on the community rates above:
- ~24 Rares (one per pack, guaranteed).
- ~6–8 Epics.
- ~1 Legendary (usually 0 or 1; occasionally 2).
- ~0.25–0.33 numbered chase parallels — so roughly one in every 3 boxes yields a chase.
- Unleashed only: ~0.17 Ultimate Rares — roughly one Baron Nashor per case of six boxes.
Simulate your own openings
Rather than argue about rates in the abstract, our Riftbound Pack Lab uses these numbers to run large-sample simulated rips against the current set. It's the fastest way to build intuition for how streaky Riftbound packs actually are — and to spot when a box you've opened wildly beats or undershoots the expected value.
Where the estimates get soft
- Print-run distribution — Riot has not disclosed print totals by rarity slot, so community rates depend on sample size.
- Print variance across regions — Chinese and Western prints have shown small distribution differences in Origins reports.
- Ultimate Rare frequency — Baron Nashor's rate is the least-sampled figure in this post. Take it as directional.
- Vendetta (July 31, 2026) not included yet. We'll update this article once meaningful box-count data lands, likely 2–3 weeks post-launch.
Common questions
Does Riot publish official Riftbound pull rates?
No. All rates on this page are community estimates cross-checked against our Pack Lab simulator. They are directionally accurate, not exact.
How many Legendaries per booster box?
Community rates put it at roughly one Legendary per 24-pack booster box on average across Origins, Spiritforged, and Unleashed. Variance is high — 0-Legendary and 2-Legendary boxes are both common.
What's the rarest card slot?
Unleashed's Ultimate Rare (Baron Nashor) is currently the rarest documented pull, roughly 1 per case of 6 boxes.
When will you publish Vendetta pull rates?
2–3 weeks after the July 31, 2026 release, once enough community box openings have been logged.
