Sword of Glacis

Gathering moisture in the air, you freeze the water, provided that there are no creatures in it. Forming it into a long sword over the head of the creature you can see. The ice sword will then fall onto the creature, for 1d8 piercing damage and 1d6 cold damage if the creature does not succeed on a DEX saving throw (DC 14)

If the target fails their DEX save, the target will receive 1d8 piercing damage and 1d6 cold damage. For the duration of the spell, the target must make a DEX saving throw at the start of each turn. If they fail the throw, target will receive another 1d6 cold damage.

If the target succeeds on their DEX save, the spell will deal half cold damage with no piercing damage, and no lingering effects.
