A scar at the center of your palm stretches down to the end of your wrist.  Black burns on the edges with the inner blue glow of your magic.

The weapon you are holding is imbued with Ymmo's power.

For the duration of 1 minute, you can use your Strength and Dexterity ability modifier's instead of just one for the attack and damage rolls of melee attacks using that weapon, and the weapon's damage die becomes a d10. 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.
