Arcane Warrior

The weapon you are holding is imbued with arcane power. For the duration, you can use your spellcasting ability instead of Strength for the attack and damage rolls of melee attacks using that weapon, and the weapon's damage die becomes a d8. The weapon also becomes magical, if it isn't already. The spell ends if you cast it again or if you let go of the weapon.

If the strength of your wisdom is sufficient, you can always perceive what the situation is. If your body moves freely in the way of strategy, if you accurately probe the mind of your adversary, you will find many ways of winning. - Miyamoto Musashi, The Book of Five Rings
