Riftbound Core Rules: Patch Notes

Published: 2025-10-24
Source: https://playriftbound.com/en-us/news/rules-and-releases/riftbound-core-rules-patch-notes/
Scope: Core Rules (CR) update only — does not affect Tournament Rules (TR)

Welcome to Riftbound’s first official Rules Update Patch. This patch updates the Core Rules (CR) and not the Tournament Rules (TR). These notes are not comprehensive or exhaustive, but draw attention to the most broad areas of focus to discuss intent and clarify the largest and most sweeping changes.

Origins has already had the initial rules release, the FAQ, and now this update. A more regular rules update cadence is anticipated in the future.

Many rules have changed their number as a result of this update. Some rules are new and numbered for the first time. Some entire sections may have moved. Changes of this nature are generally not mentioned here.

The rules updates and clarifications from the recent FAQ are present and iterated in these notes (pending chain items, triggered abilities evaluating conditions based on destination, individual card errata, etc.). There are also new clarifications and changes not mentioned in the FAQ.

Patch Notes

New Silver Rules

Silver Rules express broad rules and concepts across the game that are nearly always true. Two new rules added:

  • NEW RULE: Can’t beats can.
  • NEW RULE: “Do as much as you can” — otherwise known as DAMAYC.

Adjustments to Foundational Definitions

  • CLARIFIED: You cannot ready something that is already ready. It can be targeted with an effect that will ready it, but it will not become ready for the sake of triggers or other game effects. (Already spelled out for exhaust; ready now matches.)
  • CLARIFIED: Domain Identity is keyed off of Champion Legend.
  • CLARIFIED: Corrected vague language in the rules regarding Domain.
  • CLARIFIED: A player’s Chosen Champion is not one specific piece of cardboard, but any Champion Unit with the same name as the Chosen Champion that began the game in the Champion Zone.
  • CLARIFIED: The Champion Zone has a maximum occupancy of 1.
  • CLARIFIED: The Main Deck is secret information — it is a secret to everyone.
  • CLARIFIED: When cards are returned to players’ hands, they are returned to their owners’ hands only.
  • CLARIFIED: When cards are recycled, they are only recycled by their owner, regardless of which player is instructed to recycle them.

Minor Deckbuilding Clarification

  • CLARIFIED: Players cannot have duplicate battlefields among their 3 battlefields.
  • NEW RULE: In 2v2, partners cannot include the same battlefield across both of their decks.

Intent: Battlefields should be a source of variance and expression, undermined if both players bring the same battlefield — worse if they each bring three of the same battlefield.

2v2 Adjustments

  • NEW RULE: Allied players cannot repeat battlefields in their decks.
  • NEW RULE: Players cannot have the same Champion Legend as their partner. (This was how the game was tested and played internally.)
  • CLARIFIED: Partners win or lose together. One player conceding causes their partner to lose as well.
  • Rule 650: No change.

Card Details

  • CLARIFIED: Cards with subtitles have the subtitles as part of their name.
  • CLARIFIED: References to cards’ costs always mean their base cost.
  • NEW RULE: Defined Tags, Domains, Types, and Supertypes.
  • CLARIFIED: More clearly defined details about shorthands for Exhaust and Might.
  • CLARIFIED: Clearly defined shorthand for Domains.

Damage, Deal, and Heal

  • NEW RULE: Damage is now defined.
  • NEW RULE: Deal is now defined as a game action.
  • NEW RULE: Heal is now defined as a game action.

Bonus Damage

  • CLARIFIED: Bonus Damage is now properly defined.
  • CLARIFIED: More clearly defined how Bonus Damage interacts with the Deal action.

Bonus Damage for the most part was an easily understood fantasy (e.g., Void Seeker deals 4 damage + 1 Bonus Damage = 5 total). Needed more explicit rules about how it interacts with more complex spells and abilities.

Removal of Relevant Players and the Invite Mechanic in FFA

The “Relevant Player” system for Free-For-All has been removed. While the system created exciting table-politics potential, in practice it created situations where players were powerless to defend themselves in FFA games.

  • REMOVAL: Concept of “Relevant Players” has been stricken from the Core Rules.
  • CLARIFIED: All players always have agency to act during Showdowns and Chains in all modes.

Basic Rune Abilities

  • CLARIFIED: Basic rune abilities have Reaction. (They always did. It was forgotten.)

Pending and Finalizing

Notable functional change: Players can now refuse Deflect costs incurred by triggered abilities. This will result in the triggered ability failing to finalize on the chain.

  • NEW SYSTEM: Pending and finalizing have been added and detailed.
  • NEW SYSTEM: FEPR — Finalize, Execute, Pass, Resolve. The process through which chains are resolved, now detailed.
  • NEW RULE: Triggered abilities that incur a cost when put on the chain may be refused, causing them to fail to be finalized.

Reflexive Triggers

  • NEW RULE: Defined reflexive triggers and how to identify them.
  • NEW RULE: Defined how reflexive triggers interact with Bonus Damage.
  • CLARIFIED: Triggered abilities originating from spells are part of the spell for considerations of kill attribution, but are still abilities for the sake of effects such as “Counter a spell.”

Numbering Sections

Many sections have had numbers appended to clarify sequential processing:

  • Steps of playing a card
  • Cleanups
  • Layers
  • Steps of combat

The Steps of Combat

  • CLARIFIED: Initial Chain population sequence (Attacker → Everyone Else → Defender)
  • CLARIFIED: Focus does not pass at the end of the initial chain. (Ensures who plays first in a showdown is not reliant on whether there was an initial chain.)
  • CLARIFIED: Defined more clearly when and how the Attacker and Defender designations are gained.
  • CLARIFIED: Spelled out the end of combat sequence.
  • CLARIFIED: Assigning and dealing combat damage are now clearly and separately defined.
  • CLARIFIED: Combat Cleanup defined as a Special Cleanup.

Cleanups

  • CLARIFIED: Made the cleanup step much more robust — when they occur, what happens during them (and what doesn’t), and what order those things happen in.
  • NEW RULE: Cleanups occur repeatedly until a cleanup occurs with nothing of note occurring.
  • NEW RULE: Introduced the concept of Special Cleanups. A Special Cleanup has unique steps inserted, and if it repeats, a normal cleanup is what repeats until nothing of note occurs.

Special Cleanups happen once. If a Special Cleanup needs to repeat, it repeats into a normal cleanup.

Contested Status and Control

  • CLARIFIED: Made more clear the process of contesting battlefields (related to Attacker and Defender designations).
  • NEW RULE: Players now can’t lose control of battlefields while a battlefield is contested, even if they have no units there.
  • CLARIFIED: Spelled out how control is established, and when specifically the contested status is removed from battlefields.
  • CLARIFIED: If a player moves units into a battlefield that a differing player had moved to and opened a showdown for, the current showdown will end and a second showdown will begin alongside combat beginning. (This is called “surprise defense.”)
  • CLARIFIED: Control of a battlefield establishes control of its abilities.
  • NEW RULE: Defined the concept of neutral abilities and how to handle them.
  • CLARIFIED: Made clear that control is established at the end of a non-combat showdown.

Showdowns and Combat Staging

  • EDIT: Combat is now “staged” instead of “pending.” (Pending means more for the pending and finalize systems; combat and showdowns are Staged going forward.)
  • CLARIFIED: Showdowns are now marked as staged.

Targeting and Choosing

  • CLARIFIED: Targeting has clear definitions.
  • CLARIFIED: “Valid target” has a rote definition.
  • NEW RULE: Move destinations are a required choice — must be made at time of putting a spell or ability on the chain. You cannot choose destinations that are not valid to satisfy the conditions of a spell or ability.

Null Isn’t Zero

  • CLARIFIED: Unavailable numerical information always resolves to a null value rather than to 0.

Example: If you target a unit with Baited Hook and the unit is returned to hand before the effect resolves, its Might is treated as null. Null + 1 = null, and no unit has null as a Might. You’ll reveal the top 5 cards of your Main Deck, but you won’t get to play any of them.

Layers

Layers in Riftbound now loop. Layers apply repeatedly until each effect has been applied (or removed) once and layers have been evaluated with no objects changing. This helps Fiora actually work without being a paradox.

  • NEW RULE: Layers apply repeatedly until all applicable effects are applied or disqualified a single time and no objects have changed during one sequence of application.
  • CLARIFIED: Dependencies have been more clearly defined.
  • CLARIFIED: Method of resolving dependencies have been more clearly defined.

Triggered Ability Updates

  • CLARIFIED: Made clear how to identify triggered abilities, including “Nth time” abilities. (Terms that identify triggered abilities don’t have to appear at the start of the ability’s sentence — e.g., Sona.)
  • CLARIFIED: When the triggering event occurs at the specified N but more than one qualifying event occurs simultaneously, the “Nth Time” trigger will only trigger once.
  • CLARIFIED: Triggered abilities evaluate conditions from the destination of their object. (See FAQ for Immortal Phoenix and Viktor, Leader.)
  • NEW RULE: Several common trigger shapes have been defined: Play, Conquer, Hold, Attack, and Defend abilities.
  • NEW RULE: Attack and Defend triggers can happen once per combat, specifically the first time something gains the attacker or defender designation during that combat.
    • ⚠️ NOTE: This is a change from the FAQ. The team further tested and decided that triggering Attack and Defend triggers multiple times didn’t feel right, and rewarding moving units repeatedly in and out of combat wasn’t the intent.

Delayed Abilities

  • NEW RULE: Defined the concept of a delayed ability and how to identify them.
  • NEW RULE: Any type of ability can be delayed. Added rules to clarify how those operate with delay.

Costs

  • CLARIFIED: Made clear that replaced costs are still paid costs.

Scoring

  • CLARIFIED: Conquering on defense has been clarified through the concept of contested status.

Burn Out

  • CLARIFIED: Made the conditions to Burn Out more clear.
  • CLARIFIED: Made the conditions to repeatedly Burn Out more clear.
  • Added examples and logistics for when and how players would hypothetically infinitely Burn Out.

Add

  • CLARIFIED: ‘Add’ abilities finalize immediately like Units and Gear.
  • CLARIFIED: Focus and Priority do not pass on resolution of Add abilities.

Kill

  • CLARIFIED: Kill effect definition clarified.
  • CLARIFIED: Kill attribution rules clarified.

Hide / Hidden

  • CLARIFIED: Cards in the Champion Zone can now use their Hidden abilities.
  • CLARIFIED: Hidden costs [A], not [C].
  • CLARIFIED: Hidden’s targeting restrictions have been rearticulated as part of the broader targeting changes.
  • CLARIFIED: Hidden cards gain Reaction when played from facedown — they aren’t just played as though they have it.

Notable impact: The targeting change means Zhonya’s Hourglass no longer restricts its replacement effect to the battlefield it was hidden at.

Legion

  • CLARIFIED: Made clear the specific differences in Legion as a spell ability, play effect, and activated ability.

Accelerate

  • CLARIFIED: The cost of the ability always matches the domain of the unit that has the ability.
  • CLARIFIED: If the ability is ever on a unit with no domain or more than one domain, it becomes [A].

Recall

  • CLARIFIED: Recalls are only to the object’s base.
  • CLARIFIED: Recalls do not affect the state of the object.
  • CLARIFIED: Recalls are not moves.
