If a player controls a unit that provides "Your spells and abilities deal 1 Bonus Damage," can they deal enough damage to eliminate two 4mt units with a single spell?

The statement regarding the ability that provides "Your spells and abilities deal 1 Bonus Damage" indicates that any spell or ability a player uses will have an additional effect of dealing 1 extra damage. However, this bonus damage applies only to the spell's main damage output and does not allow for distribution among multiple targets in a way that increases the total damage dealt to those targets.

In this scenario, if a player casts a spell that would typically deal a fixed amount of damage—let's say 4 damage—it would deal a total of 5 damage (4 base damage + 1 bonus damage). If the intended targets are two units with 4mt (4 health), the damage inflicted by the player can eliminate a single 4mt unit but cannot be split or effectively doubled (as in the case of hitting both units) due to the limits of the spell's damage allocation.

Therefore, the maximum damage output would remain limited to what is indicated by the spell itself, supplemented by only 1 point from the ability. Since the spell does not deal sufficient total damage to eliminate two separate 4mt units in a single casting, the situation confirms that the player can only apply a total of 1 additional damage with their spells and abilities,
