Demonic Spikes

you touch the ground, using demonic magic to create several dark red spikes to impale your enemy. Can be used once and then must be recharged using 1 long rest and 1 short rest, or by Divine Magic to recharge only once until the DM decides Divine Magic can recharge the spikes again. Will immobilize the target for 3 turns and you must roll 1d20 to see if you hit. a 20 will kill the enemy immediately. Requires 14 minimum to hit, and only an 18-20 will damage 1 necrotic damage guaranteed, the remaining damage will be decided by DM unless a 20 is rolled. Will not kill an enemy with an AC of over 20, but will do 35 damage. Target's AC does not affect accuracy, but interference can occur to make the spikes miss. States available for Order of the Profane soul, but is really available for any blood hunter lv 3 or above. As you level up, you will get better at the spell and are more likely to hit. Every 5 levels the minimum roll to hit and deal damage will reduce by one, stopping at level 18. Leveling changes nothing else about this spell because Demonic Magic has its limits.
