Silver Sword
Weapon, major (requires attunement by a creature that has psionic ability)
- Damage: 2d6 slashing
- Properties: Heavy, Two-Handed
- Weight: 6.0 lbs.
You have a +3 bonus to attack and damage rolls made with this magic weapon. On a critical hit against a target in an astral body (as with the astral projection spell), you can cut the silvery cord that tethers the target to its material body, instead of dealing damage.
