Some stupid skill I came up with. Stigmatize me if you want.

It's a Special skill, not a Passive. Guess I should've said that in the title huh?

Base Special: "Reflect" - If unit is attacked by foe using a special attack, foe is damaged with 50% of the received attack. (CD: 3)

"Mirror" - Same effect as Reflect. (CD: 2)

"Karma" - If unit is attacked by a foe using a special attack, foe is damaged with 80% of the received attack. (CD: 4)

To clarify - the foe may be damaged during combat and before combat. The foe may die during combat because of this special, meaning that it's possible for both units to die simultaneously during combat. If the special is an attack before combat, foe's HP will be lowered to 1 if damage exceeds their current health.
