During a showdown, can a player start two different chains of actions (e.g., casting two Hextech Rays) before proceeding to combat?

Ruling: Yes, you can play multiple actions during a showdown, but not consecutively without your opponent having a chance to respond. The showdown ends when both players pass focus without creating a chain.

Sequence:

• Player gets focus and plays first action (e.g., Hextech Ray)
• Chain resolves (both players could add reactions)
• Opponent gets their turn to play an action
• If opponent passes, original player can play another action (e.g., second Hextech Ray)
• This continues until both players pass consecutively

Nuances:

• You cannot play two actions at the same time or truly "consecutively" - your opponent must have the opportunity to act or pass between your actions
