Blade of the Realms

Magically attuned to each of the Eight Realms,
the Blade of the Realms can slip in and out of reality at a thought. When wielded by a true warrior, no mortal armour can stop it.
Pick one of the bearer's melee weapons, each time you make a wound roll of 6+ for that weapon, the target suffers 1 mortal wound in addition to any other damage the attack inflicts.
