Tranquilizer Mine

Using your mechanical knowledge, you create a mine with a hidden effect that will trigger if an enemy steps near it. Choose a space near you in which you can hide your mine. Until the spell is triggered or dispelled, the mine is considered hidden. Any creature that would attempt to find the mine must be actively searching for traps and make a Wisdom (Perception) check against your Spell Save DC in order to find it.

Unless you take an action to remotely dispel the mine, at which point it becomes an inert hunk of metal, if any creature not designated at the time of casting enters a 10 foot radius of the mine, it will be triggered.

If the mine is triggered, it releases a flurry of powerful tranquilizer darts in all directions. Creatures within the radius must make a Dexterity saving throw or take 5d12 Piercing Damage and are stunned for 1 minute. On a successful save, creatures take half damage and are only stunned until the beginning of their next turn. Creatures that fail the save can make a Constitution saving throw at disadvantage against your spell save DC at the beginning of their turn in order to attempt to resist the effect; on a successful save, they are no longer stunned.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d12 for each level above 5th.
