Jodariel's Exiling Impalement

7-level Transmutation

You transform your arm into a blade of demon-horn that lances towards your enemies. Make a melee spell attack against a creature in range. On a hit, the target takes 5d10 force damage, plus 5d10 necrotic damage and suffers the exile curse for 24 hours.   A creature under the effect of the exile's curse cannot see, or be seen, by any creature except you, the caster. The cursed creature is, for the purposes of interaction with other spell effects, invisible to all creatures except you, whilst all other creatures are considered invisible to the target.   When the cursed creature takes damage, it can make a Wisdom saving throw. On a success, the curse ends. A successful remove curse spell also ends the Exile Curse's effect.
At higher levels: When you cast this spell using a spell slot of 8th-level or higher, both the necrotic, and force damage dealt increase by 1d10 per spell slot level expended above 7th.
