Which action must a player take if they can assign lethal damage to more than one unit in a showdown?

In a showdown scenario within the game, a player is required to make strategic decisions about how to allocate damage among opposing units. When the player can assign lethal damage—damage sufficient to destroy a unit—to more than one unit, it is a fundamental rule that they must assign lethal damage to at least one of those units. This ensures that the player engages actively in combat and does not neglect the opportunity to eliminate threats on the board.

Assigning lethal damage is crucial for maintaining an advantageous position in the game, as it allows players to reduce the opponent's capabilities while potentially protecting their own units. This mechanic encourages players to think critically about their choices and the impact of damage distribution during showdowns, as failing to assign lethal damage could result in missed opportunities for strategic advantage.

Alternative choices may present scenarios where the player has more freedom or independence in assigning damage, but the rules dictate that assigning at least one instance of lethal damage is mandatory when possible, reinforcing the aggressive and tactical nature of gameplay in Riftbound.
