When this hits a hero, mark them.

Piercing 1

This card is an expansion slot card and appears in the back 2 cards of The Hunted booster packs. It is not able to be used in The Hunted limited formats, including sealed deck and booster draft.
The hero becomes marked when the triggered layer resolves. If this hits a marked hero, the hero will become unmarked when hit, and then marked when the trigger resolves.

Mark - (You are marked until a hero hits you.)

Marked is a new state for a hero.
In The Hunted, there are effects that mark a hero. Some cards and their effects may depend on whether a hero is marked or not.
A hero is marked until they are hit. Once they are hit, the marked status is immediately removed and they are no longer marked. This is not a triggered effect or a game-state process.
Marking a marked hero does nothing.
If a marked hero becomes a different hero or reverts to their base hero (e.g. Arakni, Marionette; Shiyana), their marked condition persists after they become / revert their specified hero.
If a marked hero transforms into a different hero (e.g. Teklovossen, the Mechropotent; Levia, Redeemed), that hero is not marked.

Piercing X - If this is defended by an equipment, it has +X{p}.

Piercing X is a static ability that generates a continuous effect.
If an attack with Piercing is defended by multiple equipment, it does not gain +X for each defending equipment.
If an attack has multiple instances of Piercing X, each effect is evaluated and applied separately.
If an attack with Piercing is no longer defended by an equipment, it loses its +X bonus.
