Thorn of Magic

Enchant a dart with an arcane link connected to you, and hurl it with magical force at a creature you can see within range. Make a ranged spell attack. On a hit, the target takes 1d4 force damage.

In the same turn after you hit a creature with this dart, you may cast a spell or cantrip with a range of touch on that creature while they remain within range. If the spell requires an attack roll, add the force damage dealt to the roll as a bonus. If the spell requires the creature to make a saving throw, the roll receives a penalty equal to the force damage dealt. Afterwards, both the dart and the arcane link vanish.

This spell's damage increases by 1d4 when you reach 11th level, requiring an extra dart to cast.
