"This spell was Armon's attempt to copy his sister's Greatsword Spike. He always thought it a failure, but would never openly admit that."   Stabbing your blade into the ground, you summon a 5-foot-wide, 30-foot row of spectral spears to burst out of the ground and persist until the spell ends.
Any creature that enters the line for the first time on a round or starts its turn there, must make a Dexterity saving throw or take 1d6 Lightning + 1d6 Piercing damage on a fail and half as much on a success.   Ascended Spells. This spell costs 2 Spell slots to cast. A 2nd-level spell slot and a 1st-level spell slot.
