What are the pull rates of a Riftbound booster pack?

A pull rate is how often a kind of card turns up when you open a booster pack. In Riftbound: the League of Legends trading card game, the slots of a pack are fixed, so the Commons, Uncommons and Rares come in the same numbers every time. What changes from pack to pack is whether a rare slot holds something better: an Epic, an alternate art card, an overnumbered card or, far less often, an Ultimate Rare.

Riot Games has published rates for these cards, most of them for Origins, the first set, in its article on collectability. This article gives them per pack and per booster display of 24 packs.

What does every Riftbound pack hold for certain?

Every booster pack holds 14 cards from one set: seven Commons, three Uncommons, two cards of Rare or better, one foil Common, Uncommon, Rare or Epic and one rune or token. A booster display of 24 packs therefore holds at least 48 cards of Rare or better.

The first two sets had one flaw. In November 2025 Riot confirmed in its article on the launch of Origins that a very small share of single Origins packs were missing a rare card, and said that some Spiritforged packs would have the same problem until it was fully corrected from the third set, Unleashed. Riot added that every booster display of both sets still held the right number of rares.

How often do you pull an Epic?

An Epic turns up in about one booster pack in four, which is about six Epics in a display of 24 packs. Riot gave this rate for Origins. An Epic takes the place of a Rare in one of the two rare slots, and both slots can upgrade, so a pack with two Epics is possible. In Origins most Epics are champion units and signature spells: Jinx, Rebel and her signature spell Super Mega Death Rocket! are both Epics.

How rare are alternate art, overnumbered and signed cards?

The showcase printings, which carry the gold Showcase gem, are much rarer than Epics. Riot's rates for Origins are about two alternate art cards per display and about one overnumbered card per three displays. Roughly one overnumbered card in ten is also signed by its artist. Per pack, that comes to the odds below.

The four cards below show the steps for one champion: Jinx, Rebel as an Epic and Jinx, Rebel as an alternate art card, then the Jinx Legend Loose Cannon as an overnumbered card and Loose Cannon as a signed one.

Are the pull rates the same in every set?

Riot has not published new rates for Epics, alternate art or overnumbered cards since Origins. Its three overviews, The Unleashed Overview, The Vendetta Overview and The Radiance Overview, list the same slots, with these changes.

• Special printings. Vendetta added the Crystal Rose special printings, such as Kai'Sa, Survivor, and Radiance, with its release on 23 October 2026, adds K/DA ones, such as Ahri, Confident. Riot says they turn up about as often as the other alternate art cards.
• Signed cards. The one in ten rate for signed cards is Riot's figure for Origins, where all twelve overnumbered Legends have a signed version. Later sets sign only some of their overnumbered cards: 12 of the 30 in Spiritforged, and in Vendetta the nine overnumbered Legends but none of the 22 Rival overnumbers. Riot has given no rate for signed cards in those sets.
• Ultimate Rares. Unleashed brought the first Ultimate Rare, Baron Nashor, in fewer than one pack in 1,000. Riot has said that the Baron was not quite as rare as intended. Riot calls the Ultimate Rare of Radiance, the battlefield Packed Amphitheater, its rarest Ultimate Rare yet: it turns up in about 0.025 percent of packs, one in 4,000. A pack never holds more than one Ultimate Rare.
• One showcase slot in Radiance. In a Radiance pack one rare slot always holds a Rare or an Epic, and only the other can hold a showcase printing or the Ultimate Rare. For Unleashed and Vendetta, Riot lists both rare slots as able to hold one.

What are the odds in the foil slot and the rune slot?

Riot has published no numbers for these two slots. The foil slot holds a foil Common or Uncommon most of the time, and now and then it upgrades to a Rare or an Epic. The last slot holds a rune or a token. Riot says that slot occasionally holds a foil rune and, very rarely, an alternate art rune such as the Origins Fury Rune.

What are the chances of one particular card?

Divide the rate of its printing by the number of cards that share it. Riot has not said that every card of a rarity is printed equally often, so the results are rough. Origins has 42 Epics, so with an Epic in one pack in four, one named Epic turns up about once in 168 packs, or once in seven displays. The 24 alternate art champion units of Origins share about two cards per display, so one named alternate art card turns up about once in 12 displays. The same sum for one of the 12 overnumbered Legends of Origins gives about one pack in 864, or one in 36 displays, and how many packs it takes to find an overnumbered card turns that into the chances after a given number of displays.

Do the rates promise anything per display?

No. Riot gives every rate as an average over the whole print run and says plainly that the rates are not guarantees for a single pack or a single display. Packs are filled at random during manufacturing, and Riot says there is no guaranteed Ultimate Rare in any pack, box or case. A display averages two alternate art cards, but one display can hold none while another holds several.

The only promise in a pack is its slots. The averages help over many packs, for example when you work out what it takes to complete a set, but they say little about the next pack you open.

Will the pull rates change with Legacy?

The slots change with Legacy, the first set of 2027, with its release on 29 January 2027. In its announcement of 3 August 2026, Riot said that one Common slot becomes a slot that holds a Legend or a battlefield, each about half the time, so a pack will hold six Commons instead of seven. Riot made the change so that a Legend no longer takes a slot where a player hopes for something rarer. Showcase printings of Legends and battlefields stay in the slots of the overnumbered cards. Riot has not published rates for the showcase printings of Legacy yet.
