Viagra

You or a creature you touch can harness the potency of Viagra, imbuing your attacks with a transformative effect. For the duration, your melee weapon attacks deal piercing damage instead of their usual damage type. Additionally, your attacks gain a +1 bonus to attack and damage rolls.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the bonus to attack and damage rolls increases by +1 for each slot level above 2nd.
