No Errata
Q: I have a fighter equipped with Vampiric Weapon and I play Last Lunge when that fighter would be taken out of action. If that fighter takes an enemy fighter out of action with the Attack action granted by Last Lunge, removing a wound token from my fighter, what happens?
A: If, after the Attack action, the fighter has fewer wound tokens on their fighter card than their Wound characteristic, they are not taken out of action and your opponent does not gain a glory point.
