Final answer:
In the context of Valorant, backstabbing deals increased damage due to higher damage multipliers for shots from behind. Shooting through Sage's Wall, however, does not increase damage but bullets undergo penetration loss.
Step-by-step explanation:
The question pertains to the damage mechanics in a video game, likely referring to Valorant since it mentions backstabbing and hitting Sage's Wall. In Valorant, backstabbing -- that is, shooting an enemy from behind -- generally deals increased damage due to most weapons having a higher damage multiplier when hitting from behind as compared to shots landing on the front or sides of an enemy player. As for Sage's Wall, shooting through her Wall does not inherently increase the damage but rather the bullets suffer penetration loss resulting in slightly less damage upon hitting an opponent on the other side of the wall.
