Arcane Armaments

You create a melee weapon which you are already proficient with, made from arcing and flickering purple and blue arcane force. For the duration, you can use your spellcasting ability instead of Strength or Dexterity for the attack and damage rolls of melee attacks using this weapon. The weapons damage die is a d8 regardless of the weapon type, and deals Force damage on a hit. The weapon has any of the properties that the weapon it is copying also has, including its Mastery property.

The spell ends early if you cast it again or if you let go of the weapon.

Cantrip Upgrade. The damage die changes when you reach levels 5 (d10), 11 (d12), and 17 (2d6).
