What is the difference between priority and focus in Riftbound?

Ruling: Focus is who can start a chain (during a showdown with properly timed cards/abilities), while priority is who can add items to the chain. Focus is passed automatically once the item that started the chain resolves, while priority is passed manually.

Sequence:

• When you get focus, you also get priority
• You retain focus throughout that chain
• Priority passes between players as chain items resolve
• After each chain item resolves, the player who controls the next item on the chain gains priority first to keep adding stuff to the chain

Nuances:

• You can keep priority to put more stuff in the chain for as long as you want and can
• You can add stuff to the chain after items in the chain have already resolved
