Toxic Tongue

"There once was a famous wizard of great renown who abandoned the art of magic and retreated to a hermitage deep in an ancient forest. She enjoyed roaming what became known as her woods in various animal shapes. Legend says she created this spell to enhance her ability to defend her grove. I acquired it from the grandson of one of her druid apprentices."

 A black fluid dribbles from the corner of your mouth as your saliva becomes a virulent poison. For the duration, you can use your action to either spit the poison at a foe or apply it to a weapon. To spit the poison at a foe, choose a target you can see within 30 feet of you. Make a ranged spell attack. On a hit, the target takes 4d6 poison damage and is poisoned. At the end of each of its turns, the target can make a Constitution saving throw. On a success, the effect ends.

As a bonus action, you can apply the poison to a weapon you wield. The next creature you hit with the weapon takes 4d6 poison damage and is poisoned. At the end of each of its turns, the target can make a Constitution saving throw. On a success, the effect ends. You can apply the poison either to a manufactured or natural weapon, including your own bite attack if you have one. The poison remains on your weapon until you make a successful attack or until the spell’s duration ends, whichever comes first.
