Rare Arcane, Transmutation, Conjuration

Enchantment
You gain a +1 bonus to attack and damage rolls made with this magic weapon.

Once you can use an action to turn the coil designs on this rapier into two Giant Poisonous Snakes, creating them within 10 ft. of you. The summoned snakes are friendly to you and your companions. In combat, the snakes share your initiative count, but take their turns immediately after yours. They obey your verbal commands (no action required by you). If you don’t issue any, they take the Dodge action and use their move to avoid danger. The snakes remain for 1 minute or until they drop to 0 Hit Points. When the snakes disappear they return to the blade. The Rapier can't be used this way again until you finish a long rest.
Enchantment Weapon Skill
Venomous Lash. As part of your attack action, you may spend one weapon skill use to replace one of your attacks made using this weapon with a Venomous Lash attack. On a hit the target suffers the weapon’s normal effects, and takes an additional 1d4 poison damage. The target then makes a constitution saving throw against your weapon save DC, becoming poisoned for 1 minute on a failed save. On a successful save the target is not poisoned. The target repeats the saving throw at the end of each of its turns, ending the poisoned condition on a success.
