Riftbound Stun: what it does
GlossaryStun is the Riftbound game action of rendering one or more units Stunned — a binary state that stops a unit contributing its Might to combat damage. A Stunned unit can't be Stunned again while it's already in that state, and it loses Stunned automatically during end-of-turn cleanup, but it still needs damage equal to its full Might to actually be killed.
What being Stunned actually does
A Stunned unit is simply skipped over when combat damage is dealt — its Might doesn't count toward the damage its side deals that combat. It's a binary status: a unit is Stunned or it isn't, so re-Stunning an already-Stunned unit changes nothing and won't trigger effects that care about the act of stunning something. Stunned wears off during step 3d of end-of-turn cleanup.
Stun vs killing a unit
Stunning takes a unit out of a single combat's damage math without removing it from the board — it still needs to take damage equal to its full Might (not a reduced amount) to actually die, and it's back to normal the following turn. That makes Stun a tempo tool for winning one specific fight, not a way to permanently deal with a threat. See the Game Actions guide for how it compares to Riftbound's other combat-disrupting effects.

What does Stun do in Riftbound?
A Stunned unit doesn't contribute its Might to combat damage — it's skipped over in the damage step, though it's still a valid combatant otherwise.
Can you Stun an already-Stunned unit?
No further effect happens — Stunned is a binary state, so stunning a unit that's already Stunned changes nothing.
When does Stunned wear off?
During end-of-turn cleanup, specifically step 3d — a Stunned unit is back to normal by the start of the next turn.
Does a Stunned unit still need full damage to die?
Yes — a Stunned unit still requires damage equal to or greater than its full Might to be killed; being Stunned doesn't make it easier to kill.
