Ball of Dark Goop

The Caster changes any dirt in his hand and changes it into 3inch radial  ball of black goop. The Wizard throws the goop at an enemies face making a range attack roll -3. A successful hit deals 1d4+3 damage to the target. The Target makes a saving throw vs necrotic damage. If successful takes half damage and is only blinded for 1 round. If the saving throw fails the target takes full damage and is blinded and silenced for 2 rounds. If the caster is level 11 the target gets no saving throw
