Warmind

You magically bond yourself to a single weapon. For the duration, you are considered proficient with the weapon, and you can use your spellcasting ability modifier instead of Strength or Dexterity for attack and damage rolls with the weapon. Any time a creature enters your reach while the spell is active, you can use your reaction to make an Opportunity Attack against that creature. On your turn, you can use a Bonus Action to make a single attack with the weapon. The spell ends if you are ever not holding the weapon you used as a material component.
