Can you play multiple Actions during a showdown chain, or only Reactions after the first Action?

Ruling: Once you play an Action to start a chain, you can only play Reactions during that chain. However, after the chain resolves, Focus passes and you will get another opportunity to play Actions before combat damage.

Sequence:

• The contesting player (attacker) gains Focus first during showdown and can play an Action to start a chain
• Both players can only play Reactions until everyone passes and the chain resolves
• After the chain resolves, Focus automatically passes to the next player
• Each player may play one Action per Focus
• This continues until both players pass, then combat damage occurs

Nuances:

• If damage spells deal damage equal to a unit's might during a chain, the unit dies before combat damage
• If only might modifications occur (no damage dealt), the unit survives until combat damage cleanup
