Riftbound Vendetta Rules FAQ - The Rulings That Overrule the Rulebook

Riot published the Vendetta Rules FAQ at 01:00 UTC on 14 August 2026, and buried in the preamble is a sentence that changes where you look things up:

The FAQ is a collection of official rulings. In places where the FAQ differs from the Core Rules Document, the FAQ takes precedence.

That puts the Core Rules PDF in second place. Riot adds the escape hatch - "when a new Core Rules Document is released, it will take precedence over any points that differ" - but until that drops, the article is the authority.

It is also the first FAQ Riot has written for a worldwide simultaneous release, and the company is openly unhappy with its own timing. Release too early and you miss what players actually find confusing; release too late and nobody can prepare a deck for an event. Riot's words: "For future sets, we're looking to try different models that might reduce some of the pain points players are feeling with this timing."

If you have not read the base game yet, start with how to play Riftbound. This is the edge-case layer on top.

The FAQ now outranks the Core Rules

Practically, that precedence line means three documents are live at once, in this order: the Vendetta Rules FAQ (14 August), the Vendetta errata article (23 July), and the Core Rules Document. Where they disagree, the FAQ wins, then the errata, then the rulebook.

The FAQ also fixes shorthand you will see throughout it. [E] is exhaust, [M] is Might, [A] is one power of any domain, and [C] is one power of this card's domain. The wrinkle is that [C] in an Accelerate cost takes the domain of the unit, or becomes [A] if that unit has no domain or several.

Riot just reversed one of its own rulings

This is the headline for anyone who has been playing since winter.

In the Spiritforged FAQ, published 14 January 2026, a player asked whether attaching Svellsongur to Aphelios, Exalted gives him a second copy of his attach trigger in time for both to trigger. Riot's answer then was unambiguous: "He does have the second copy of his ability in time, and it will trigger."

The Vendetta FAQ says that is now wrong. In Riot's own words: "the answer in the Spiritforged FAQ is no longer true: if you attach Svellsongur to Aphelios, he will not trigger twice."

Nothing about Svellsongur changed. What changed is the machinery underneath it, and that reversal is a good reason to re-check any interaction you learned from an older FAQ rather than assuming it survived the Vendetta rules update.

Equipment attaches first, then does its trick

Here is the mechanism that killed the Aphelios trick.

As of the Vendetta rules update, effects like Svellsongur and Shady Spectacles are replacement effects. They replace the event of the equipment being attached with that event plus whatever the card specifies. The two halves are not simultaneous, and the order is fixed:

• Svellsongur: attach, then copy the equipped unit's text to Svellsongur's effect text for as long as it stays attached.
• Shady Spectacles: attach, then choose a friendly unit and make the equipped unit a copy of it for as long as it stays attached.

Because the attach executes first, Svellsongur does not yet carry the copied text at the moment the attachment happens. Aphelios sees one attach event, not two.

The same logic runs the other way. If an opponent's Akshan, Mischievous steals your equipped Shady Spectacles, the old equipped unit loses its copy effect, Akshan attaches, and only then does he become a copy of a friendly unit his controller chooses. If they pick Aphelios, the attach event has already finished and the newly copied trigger never sees it.

Two smaller consequences worth banking:

• Copy effects do not copy status. Empowered is a status, not a printed trait, so equipping Shady Spectacles onto an unempowered unit and copying an empowered one leaves it unempowered. Might modifiers, buffs, Temporary, attacker and defender designations all stay put on the original object too.
• Detach and reattach refreshes activated abilities. Each instance of a copied ability is a different ability. A Sand Soldier copying Azir, Ascendent can use the copied activated ability, detach the Spectacles, reattach them to the same Sand Soldier as a copy of the same Azir, and use it again.

Kayle stacks a status the rules call binary

Kayle, Justified is a 3-Energy, 3-Might Order champion from Vendetta, and Riot describes her as an exception to how the empowered status works everywhere else. The FAQ states that for Riftbound cards other than Kayle, empowered is binary - you have it or you do not. Kayle uses the golden rule that card text supersedes rules text to turn it into a stacking status, up to three.

Two rulings follow from that, and both are easy to get wrong:

• Disempowering her removes one status, not all of them. A Kayle empowered three times who eats a disempower is still empowered twice, and still has +4 Might from the remaining stacks.
• You can activate her empower ability while she is already empowered. Below three stacks she gains one. At three stacks the ability still activates legally, it simply does nothing on resolution.

That second point matters because most Empower abilities on other cards read "Use only if not Empowered." Kayle's does not.

Gangplank needs the event to actually happen

Gangplank, Naval is a 6-Energy, 6-Might Body champion whose empowered ability is a replacement effect, and the FAQ spends four separate questions on the same principle: a replacement effect needs a real event to replace. No event, no replacement.

That last row has arithmetic worth walking through, because it is the most counter-intuitive result in the document. Swap calculates the Might difference first and generates two effects, an increase and a decrease. With a 2-Might unit opposite a 6-Might empowered Gangplank, the replacement fires after the difference is calculated: the small unit goes 2 to 6, and Gangplank goes 6 to 9. Riot concedes this "is not immediately obvious based on how the swap game action rules are written."

The same replacement logic applies to Mel, Newly Awakened. Her empowered ability adds -1 Might to what a spell or ability of yours gives to a unit it chooses. Cast Moonfall and only the chosen unit takes -3; every other enemy unit at that battlefield still takes -2, because only one of them was chosen.

Combat damage effects moved to assignment

The Vendetta rules update changed something structural, and the FAQ gives it a worked example.

Previously, prevention effects applied at combat damage assignment while damage-increasing effects applied when damage was dealt. Now every replacement effect that would modify combat damage applies at assignment. Riot's patch notes are blunt about the trade: assignment maths gets harder, timing gets consistent.

So a 4-Might unit carrying both Ki Barrier and Lotus Trap against a 4-Might defender gives you an ordering choice, and the two orders are genuinely different:

• Ki Barrier first: your unit takes no damage, and 3 damage prevention remains on it.
• Lotus Trap first: your unit takes 1 damage, and no prevention remains.

You order the replacement effects on your own unit, so this is a decision, not a coin flip. Free value if you know it, a lost unit if you do not.

Can't beats can, and Baron Nashor is the exception

Perched Grimwyrm is a 4-Energy, 5-Might Fury dragon from Spiritforged reading "Play me only to a battlefield you conquered this turn." Dragon Roost lets you pay [A][A] to play a dragon there. The two do not combine.

In Riftbound, can't beats can. Grimwyrm's restriction is a "can't", Dragon Roost's ability is a permission, and a permission cannot overcome a restriction. If you have not conquered Dragon Roost this turn you cannot play Grimwyrm there at all, even if you conquered a different battlefield - and if you have no legal location after paying, the whole play is undone and the card returns to where it came from.

Baron Nashor behaves differently for a reason worth learning, because it generalises. His passive generates a delayed replacement effect - "I enter there" - which replaces the event of him entering anywhere else. Replacement effects get around restrictions on where you may play units. Permissions do not. When you read a location-fixing card, the question is always which of the two it is.

A related ruling: when two mandatory positive requirements genuinely contradict, you pick one and ignore the rest. Temporal Breach telling you to play your Elder Dragon to base while Dragon Roost's paid cost says play it to the Roost is a free choice between the two.

How to name a card whose name you forgot

Naming cards, types and tags is new in the Vendetta rules update, and the rules are friendlier than expected.

The hard limit first: you cannot name something that does not exist in Riftbound. Riot's own examples are the "Locke" tag, the "totem" type, and a card called "Lingering Tentacles" - none printed on any card or token, none nameable.

Beyond that, you do not need the exact name. Any information that uniquely identifies the card works. Riot's examples include "the [3] spell with Flow that makes tentacles", "the red Kai'Sa", and "Illaoi". The one failure mode is ambiguity: saying just "Kai'Sa" when two or more cards answer to it means you have not named a card at all.

Timing note for Fallen Feline, the card that triggered this rules work: you can react to its play effect before its controller names a spell, but once the ability resolves you are too late, because by the time you know the named spell you can no longer play it.

Ignored versus negated, the bug Riot admitted

The most useful section of the FAQ is also the one Riot flags as a mistake. A small rule added in the Vendetta update made the linked-instructions rules too broad, with the result that playing Ride the Wind on your unit at Vilemaw's Lair and trying to move it to base readies it. Riot calls this "smoothing out a bug" rather than a real change.

The fix is a clean two-way split:

• Ignored means the instruction was not performed because it mistargeted - the object was not a legal target on resolution. Ignored instructions take their linked instructions down with them.
• Negated means something stopped the instruction: a replacement effect, an ability like Vilemaw's Lair saying units can't move from here to base, or a game action such as Buff or Ready performed on a unit already in that state. Negated instructions do not drag their linked instructions along.

Riot's four Hidden Blade examples make the distinction concrete. Hidden Blade kills a unit at a battlefield and its controller draws 2:

Rows two and four look identical at the table and resolve differently, which is exactly the sort of thing that decides a match.

Eight cards got errata, and the gallery has not caught up

The 23 July errata article covers eight cards across three sets. Five are pure wording cleanups that fold "If you do" constructions into "to" phrasing - Draven, Vanquisher; Emperor's Dais; Fizz, Trickster; Diana, Lunari; and Astral Heron. Three change something you can actually misplay:

• Stalking Wolf went from "You may play me to its battlefield" to "You may [Ambush] me to its battlefield", which pins the play to the Ambush keyword and its restrictions rather than leaving it as a loose permission. Our keyword breakdown covers why that distinction bites.
• Gangplank, Naval gained the words "this turn" on his +3 Might, which the printed card does not say.
• Resonating Strike had its Reaction reminder text corrected from "(Play on your turn or in showdowns.)" - which is Action's reminder text, printed on a card that has Reaction - to "(Play any time, even before spells and abilities resolve.)"

One practical warning. Checking the official card gallery on 14 August 2026, the ability text shown for Gangplank, Naval, Astral Heron, Stalking Wolf and Resonating Strike is still the pre-errata wording. Printed cards obviously cannot update themselves, but the gallery's text field has not been updated either, so it is not the errata of record. The errata article is.

Four things Riot says it will fix later

The FAQ is unusually candid about its own loose ends, and each of these is a spot where a future Core Rules Document may move the answer:

1. Iascylla's templating. Her delayed trigger references the battlefield she held, while Azir, Sovereign's attack trigger checks the battlefield he is at on resolution. Riot says future sets use "more precise templating and wording for abilities like Iascylla's."
2. Rebuttal's remade choices. You may remake any number of targets or modes, and any choices you decline to remake must be legal. Riot: "We'll look at shaping up this section in a future rules update."
3. Swap and Gangplank. The +3 Might result above does not fall out of the swap rules as written. Riot: "We will clarify this in a future rules update."
4. Linked instructions. The ignored-versus-negated split above is the promised clarity for a rule the Vendetta update over-extended.

Quick reference

• The FAQ beats the Core Rules until a new Core Rules Document ships.
• Svellsongur no longer double-triggers Aphelios, Exalted. The January ruling is dead.
• Equipment attaches first, then executes its copy effect. The two are not simultaneous.
• Copy effects do not copy the empowered status, or any other temporary modification.
• Kayle, Justified holds up to three empowered statuses; disempower strips one.
• Replacement effects need a real event. Already stunned, or reduced to -0 Might, means nothing to replace.
• All combat damage replacement effects now apply at assignment, and you order your own.
• Can't beats can. Permissions lose to restrictions; delayed replacement effects beat both.
• Naming works by unique description, not just exact names - but never for cards that do not exist.
• Ignored kills linked instructions. Negated does not.
• The card gallery still shows pre-errata text for four cards. Trust the errata article.

If you are heading to a Nexus Night or a Regional Qualifier before Radiance lands in October, the ignored-versus-negated table and the Ki Barrier ordering choice are the two that will actually come up. The rest is worth knowing so you do not argue about it for ten minutes and pick up a slow play warning.
