You gain a Bonus to Feint attempts equal to the weapon’s Tier.
The weapon deals full Physical damage to creatures benefitting from the Incorporeal boon. You gain a Bonus to attack and damage rolls against such creatures equal to the weapon’s Tier.
You can use the weapon to Parry attacks originating from creatures with the Incorporeal boon that target your Reflex saving throw as if they were targeting your Defense saving throw.
When you make an attack with the weapon against the Defense DC of a creature that is not benefitting from the Incorporeal boon, you can spend 1 charge of Mana Flux or Inspiration to cause your weapon to become ethereal, allowing you to target the creature’s Reflex DC instead of its Defense DC with that attack. Another Ghostly Weapon can Parry this attack as if it were targeting their Defense DC.
