Vo's Botanic Nightmare

You can produce up to 20 Twilight Crane-petal flowers, which when harmed produces a noxious gas that induces fear based hallucinations, across a specified 20ft square patch of land within the casters sight. When exposed to the gas the target takes 2d6 psychic damage and must make a constitution saving throw to endure the effects of the poison, on a failed saving throw the target rolls attacks with disadvantage for the remainder of combat or until the spells effects end.

The caster can produce the flowers in any arrangement of their choosing within the area of effect but they cannot alter the physical appearance of the flower which stands 2ft out of the ground and produces an illuminating blue glow. The caster has no tangible control over the hallucinations of those afflicted by the gas however the hallucinations may be subject to verbal or physical influence. The spells effects end if the target sustains physical damage, they are incapacitated or the caster loses concentration.

At higher levels. When cast with a spell slot of 3rd level or higher the psychic damage increases by an additional 1d8 up to a maximum of 5d8 and 2d6. When cast using a 9th level spell slot the spell changes to include; the ability to alter the physical appearance of the flowers, +10 to flower maximum, +20 cubic feet to spell area, targets can withstand up to 20 points of physical damage before it causes the spell to end and the caster has slight control over the hallucinations of the target (ie; creatures, locations or single phrases produced in the hallucinations).
