You summon 30 spectral swords 30ft in the air above a point you choose within range. Each creature in a 30ft-radius of that point must make a 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 3 rounds and can be used by friendly creatures.
They act like normal longswords, dealing 1d8+4 slashing damage and disappearing after 1 hit.
If an unfriendly creature attempts to use such a weapon, they take 1d6 psychic damage and the sword disappears.   Ascended Spells. This spell costs 2 Spell slots to cast. A 3rd-level spell slot and a 2nd-level spell slot.
