Can Wages of Pain kill units or just leave them with 0 or negative Might?

"Wages of Pain" is a spell that deals damage to a unit. Whether it kills a unit depends on the unit's current Might and the amount of damage already marked on it.

According to Rule 142.2.a, a unit is killed if it has "nonzero damage marked on it equalling or exceeding its Might."

Because "Wages of Pain" deals 3 damage:

• If the target unit has 3 or less Might, and the total damage marked on it (including the 3 from this spell) equals or exceeds its Might, the unit will be killed.
• If the target unit has more than 3 Might, it will not be killed by this spell alone, unless it already had enough damage marked on it to reach its Might threshold.

Important Clarification on Might: While some effects in the game reduce a unit's Might (which can result in 0 or negative Might), "Wages of Pain" is a damage-dealing effect, not a Might-reduction effect. It does not change a unit's Might; it marks damage on the unit.

As noted in RiftJudge FAQ #8477 and Rule 142.2.a, units do not die from having 0 or negative Might alone; they must have non-zero damage marked on them equal to or exceeding their Might. Therefore, "Wages of Pain" can certainly kill a unit if the damage it deals (plus any existing damage) meets that lethal threshold.
