Until the spell ends, beautiful flower petals of lethal toxicity rain down in a 300-foot-tall cylinder with a 30-foot radius centered on a point you choose within range. Creatures within the spell’s area cannot be resistant or immune to poison damage. When you cast the spell and at the start of each of your turns, you subject each creature in the spell’s area to one of the following poisons.
Delphinium Dose. A creature subjected to this poison must succeed on a Constitution saving throw or take 40d8 poison damage or half as much on a success.
Gloriosa Lily Pollen. A creature subjected to this poison must succeed on a Wisdom saving throw or take 20d8 poison damage and become incapacitated until the start of its next turn. A successful saving throw halves the damage.
Hydrangea Venom. A creature subjected to this poison must succeed on an Intelligence saving throw or take 10d8 poison damage or half as much on a success. On a failure, the creature suffers violent delusions for the duration of the spell. During that time, it rolls a d10 and subtracts the number rolled from all its attack rolls, saving throws, and ability checks. The affected creature can attempt an Intelligence saving throw at the end of each its turns, ending the effect on itself on a success.
Nightshade Nectar. A creature subjected to this poison must succeed on a Strength saving throw or take 12d8 poison damage and have its speed reduced to 0 until the end of its next turn. A successful saving throw halves the damage and causes its speed to be halved until the end of its next turn instead.
