Must be a Wraith to equip.
If you deliver the killing blow to an enemy Creature, you may immediatly discard this Upgrade to place a new, non-unique Wraith in the play area under your control. Place the Wraith anywhere within Range 1 of where the original Creature recieved lethal damage that is not overlapping another figure.
The new Wraith does not equip any Upgrades. If you are defeated, the new Wraith is immediatly defeated.
