Bloodletting Lance

You draw forth a jagged, light draining lance, flinging it at a creature you can see in range. Make a ranged spell attack against the creature. On a hit the creature takes 6d6 necrotic damage.

A creature damage by this spell cannot regain hit points until the spell ends; the spell ends if the creature is targeted with a remove curse spell cast at the same level as the lance.

At Higher Levels: When this spell is cast using a spell slot of 4th level or higher, the duration increases to 4 hours at 4th level, and 8 hours at 5th level. At 6th level and above this spell no longer requires concentration and lasts for 24 hours. At 9th level this spell lasts until cured by a spell of equal power. Additionally for each slot above 3rd, the damage of the spell increases by 1d6.
