Each creature in a 30-foot-radius of that point must make a DC 14(DC 20 in stealth) Dex Save taking 3d8 slashing on a failed save, or half as much on a successful one.
These swords remain implanted in the ground for 6 rounds and can be used by friendly creatures.
They act like normal longswords, dealing 1d8+4 slashing damage and disappearing after 1 hit.
Any unfriendly creatures attempting to use one takes 1d6 psychic and the sword disappears.
