What is the difference between Focus and Priority in Riftbound?

Ruling: Focus determines who can play an Action during a Showdown when there is no chain. Priority determines who can play a Reaction during a chain.

Sequence:

• Player with Focus plays an Action during Showdown Open State
• Priority passes between players as they play Reactions on the chain
• Focus remains with the original player throughout the entire chain
• When the chain fully resolves, Focus passes to the next player
• Priority passes along with Focus
• The new Focus player can now play an Action

Nuances:

• Focus exists to prevent a player from playing multiple Actions in a row without other players getting a chance to play Actions during a Showdown
• Focus rotates around players, tracking who gets first opportunity to play an Action when the chain resolves or someone passes Focus
• Priority rotates during chain resolution, tracking who can play Reactions
