How does priority work during a Showdown in Riftbound, specifically regarding when Reaction cards can be played, when Action cards can be played after chains resolve, and how passing priority works?

Question

Accepted Answer

Ruling: Reaction cards can be played anytime Action cards can be played, not just in response to Action cards. When a chain resolves fully, focus passes to the player who didn't start the chain, who now has priority to play actions.

Sequence:
- When a chain is created, the player who controls the topmost item gets first priority to react
- Only when that player passes priority can the opponent react
- If both players pass priority on a card, that card resolves
- When things resolve off the chain, both players get priority again (starting with the player who owns the next link on the chain)
- After a chain resolves fully or a player passes without playing anything, the other player gets a window to play actions
- To play multiple cards during your priority window, you must hold priority and play them consecutively; passing priority to your opponent counts as passing

Nuances:
- For the Initial Chain (created by "When I attack/defend" abilities), the attacker retains focus after it resolves
- For each chain afterwards, focus shifts to the next player
