Riftbound Disarm Explained: The Leaked Radiance Mechanic
The short version
- Disarm is a leaked combat mechanic from Riftbound: Radiance, reportedly weakening an enemy unit's Might when the Disarm unit attacks.
- It's the reported mirror image of Assault: Assault gives the attacker +X Might; Disarm instead lowers an enemy unit's Might — a debuff aimed outward rather than a self-buff.
- It reportedly pairs with direct-damage spells like Falling Star — shrink a blocker's Might first, and a fixed amount of damage goes further toward lethal.
- Not officially confirmed. This is sourced to a photo of Riot's own PAX West demo material, not a Riot announcement — see the full leak roundup for the source.
Disarm is one of three new mechanics reportedly leaked from Riftbound: Radiance ahead of the set's 23 October 2026 release — photographed on a physical rules-reference card at Riot's own PAX West demo table and shared publicly by Riftbound content creator AskJoshy. It has not been confirmed by Riot. Here's exactly what leaked, how it reportedly compares to an existing keyword, and what's still unknown.
"When this unit attacks, decrease the Might of an enemy unit here."
How Disarm reportedly works
- Trigger condition: the Disarm unit attacks. The effect is tied to attacking, not to being played or to any other timing.
- Effect: it lowers an enemy unit's Might present at that battlefield.
- It reads as a repeatable, built-in unit ability, not a one-time removal spell — the leaked wording describes something the unit does every time it attacks, not a single-use effect.
Disarm vs Assault: the same combat moment, opposite target
This is the comparison the leak's own source draws directly, and the rules text backs it up. Assault gives the attacking unit +X Might for the duration of combat — a self-buff that only applies while that unit is on offense. Disarm, as leaked, instead takes Might away from an enemy unit when this unit attacks — a debuff aimed at the opponent's board rather than a boost to your own stats. Same trigger window (attacking), opposite target and opposite direction.
Pairing Disarm with direct damage
The leak's caption suggests Disarm "can pair well with direct damage spells like Falling Star" — a real card already in the game: Falling Star is a Fury-domain Spell from the original Origins set. The logic holds up even without knowing Disarm's exact numbers: shrink a blocker's Might first, and a fixed amount of direct damage goes a lot further toward actually killing it. If Disarm decks end up leaning on that kind of stacked-damage plan, it would put them in the same lane as Fury's existing direct-damage tools rather than introducing a brand-new archetype from scratch.
How Disarm compares to Deploy and Showoff
Disarm is one of three mechanics in the same leak. Deploy is a Gear keyword tied to holding a battlefield; Showoff is a modal reveal effect triggered on play. The three don't appear designed to combo directly with each other the way Vendetta's Empower, Flow and Burn were — see the full leak roundup for the source photo and all three side by side.
Is Disarm officially confirmed?
No. This is reported from a fan photo of Riot's own physical demo reference material at PAX West, not a Riot announcement. We'll only add Disarm to our verified keyword glossary — the way Empower, Flow and Burn were added for Vendetta — once its wording can be checked against Riot's own Core Rules PDF or an official card image. Until then, treat everything on this page as reported, not settled.
Frequently asked questions
What is Disarm in Riftbound?
As leaked from a Riot demo at PAX West: "When this unit attacks, decrease the Might of an enemy unit here." It reportedly weakens an enemy unit's Might as part of attacking, rather than boosting the attacker's own stats.
How does the Disarm mechanic work?
As leaked: when a unit with Disarm attacks, it decreases the Might of an enemy unit present at that battlefield. It reads as a repeatable, built-in unit ability rather than a one-time removal spell.
Is Disarm the opposite of Assault?
That's how the leak's own source frames it, and the wording supports the comparison: Assault gives the attacker +X Might while attacking — a self-buff. Disarm, as leaked, instead lowers an enemy unit's Might when this unit attacks — a debuff aimed at the opponent's board.
Does Disarm work with direct damage spells?
The leak's own source suggests pairing Disarm with direct-damage spells like Falling Star — a real Fury-domain Spell from the Origins set. Shrinking a blocker's Might first would make a fixed amount of direct damage go further toward actually killing it, though Disarm's exact numbers aren't known yet.
Is Disarm confirmed by Riot?
No. This is reported from a fan photo of Riot's own physical demo reference material at PAX West 2026, not an official Riot announcement or Core Rules update.
How is Disarm different from Deploy and Showoff?
Disarm weakens an enemy unit's Might on attack; Deploy is a Gear keyword tied to holding a battlefield; Showoff is a modal reveal effect triggered on play. All three reportedly leaked together but don't appear designed to combo directly.
