Circle of Toxins

Druids of this circle learn how to best utilize the toxins and poisons to harm or help those they see as helpful or hindering to their way of life or to nature itself. They know best how to use the potency of these toxins to its absolute fullest, in which they bring the eyes of fear, disapproval, and respect from the other Druid circles. For some, poison is a terrible blight on the world. For these Druids, it's the best way to end a threat and also something to be respected and feared at the same time.

Knowledge of Poisons

Beginning when you take this druid circle at 2nd level, you gain proficiency with Poisoner's Kits.

Toxic Exposure

Time spent around the natural poisons of the land have hardened your body to resist the terrible afflictions by these toxins. Beginning when you take this druid circle at 2nd level, you gain resistance to poison damage and advantage with saving throws against the poisoned condition. 

Poisoned Strike

Whenever you attack with a melee attack, you deal an additional 1d6 poison damage to all your melee attacks. This damage scales to 2d6 at 6th level, 3d6 at 10th level, and 4d6 at 14th level. 

Toxic Applications

As you spend more time and expose yourself more to these toxins, you learn how to best use these toxins against the foes of nature. Beginning at 6th level, you can create a number of toxic vials equal to your Wisdom modifier a day. It takes a bonus action to apply this toxin to a melee weapon or a projectile such as an arrow. When a target is struck with an applied weapon or projectile, the target must succeed on a Constitution saving throw with a DC of 15 or take 3d10 poison damage on a failed save and is poisoned or half damage and not poisoned on a success. 

Toxic Mastery

Time spent around the virulent toxins of the world has bestowed upon you a natural defense against these toxins. Beginning at 10th level, you now gain an immunity to poison damage and you can no longer be poisoned. You also gain access to the spell Vitriolic Sphere and is always prepared and doesn't count towards your list of known Druid spells. 

Overwhelming Blight

You've spent enough time examining the virulent nature and devastating effects it has on the denizens of the world, whether they be plant, humanoid, or monster. At 14th level, whenever you cast a spell that causes damage, you can change the damage type to poison damage a number of times equal to your Wisdom modifier. Also, whenever you deal poison damage, the target's resistance to poison damage decreases one level; from immunity to resistant or resistant to no resistance.
