What happens to a unit when it reaches the end of its turn?

When a unit reaches the end of its turn, damage is removed from it. This is an important mechanic in many strategy games like Riftbound, as it encourages players to utilize their units effectively within a turn without the fear of accumulated damage carrying over into the next. The removal of damage at the end of each turn allows players to strategize and make use of their units regularly, enhancing gameplay dynamics such as timing and resource management.

The other choices provide different scenarios that do not align with how units operate at the end of a turn. For instance, a unit remaining active for the next turn does not capture the notion of how damage functions in the game, while being permanently removed from play would suggest a harsh consequence not typically associated with the end of a turn. Doubling power is also a gameplay mechanic but is not related to the general handling of damage during a turn's conclusion. Understanding that damage resets can impact how players approach their strategies is crucial for effective gameplay.
