A barely visible bead of light slowly traces the outline of this weapon.

When you strike an extraplanar creature of 26 Hit Dice or fewer while wielding a weapon that has this property, you can activate the weapon to banish that creature back to its home plane (Will DC 20 negates). A creature so banished cannot return for at least 24 hours. A creature that succeeds on its save cannot be banished by the same weapon for 24 hours. If the creature struck has damage reduction that requires a particular weapon alignment or special material to overcome, increase the save DC by 2 for each such property shared by the weapon. For example, if you use a holy banishing cold iron weapon against a hezrou (damage reduction 10/good), the save DC would increase by 2, while against a marilith (damage reduction 10/good and cold iron), the save DC would increase by 4.
The banishing property can be activated three times per day.
Projectile weapons bestow this property upon their ammunition.
