Arcane Strike

With a quick flourish you surround your weapon with a field of arcane energy, you make one attack with the weapon used in the spell’s casting. The attack uses your spellcasting ability for the attack and damage rolls instead of using Strength or Dexterity. If the attack deals damage, it deals Force damage instead of the weapon's normal damage type.

The Shield spell blocks this attack.

Cantrip Upgrade. The attack deals extra Force damage when you reach levels 5 (1d6), 11 (2d6), and 17 (3d6).
