Venom Spray

The caster spits a spray of venom at an adjacent victim. The target must make a con save versus the casters spell DC or be poisoned for 1 minute and take 3d4 poison damage, the target may make a con save at the end of each of its turns to negate the poisoned condition. If the target saves it takes half damage and is not poisoned. 

At higher levels the spell inflicts 2d4 for each spell slot of 3rd level or higher.
