What does the term “Combat Damage” refer to in the context of the game?

The term "Combat Damage" in the context of the game specifically refers to the damage that is assigned to units during combat. This process occurs when two or more units engage in a battle, where the attacking unit deals damage to the defending unit and vice versa, depending on the game's mechanics. Understanding this concept is crucial as it influences strategy regarding unit health and combat interactions, impacting the outcome of battles.

In contrast, damage dealt to a player's life points pertains to direct attacks on the player, which is a different aspect of gameplay. Damage inflicted on one’s own units does not fall under the traditional definition of combat damage, as it pertains to self-inflicted harm rather than interactions between opposing forces. Lastly, damage calculation during spell casting pertains more to the resolution of spells rather than the actual combat phase, where unit damage interactions take precedence. Thus, the correct focus on unit interactions during combat is what makes the chosen answer accurate.
