Venom Trap

Tapping your foot to the ground below you, you place a semi-translucent purple trap where you stand. Once triggered, it will do a d6 of poison damage and inflict the Poisoned condition if it isn't dispelled within five rounds (half a minute). If the target is unable to neutralize the poison upon a CON save, they will take a d6 of damage for each of the five remaining rounds it is active and have disadvantage on Ability Checks.
