Plaintiff must plead a conspiracy claim "with some degree of specificity[,] and vague or conclusory allegations that are unsupported by material facts will not be sufficient to state a claim." Wuliger v. Keybank Nat'l Ass'n, No. 3:02 CV 2160, 2006 WL 42186, at *6 (N.D. Ohio Jan. 6, 2006). Further, conspiracy claims in Ohio are "derivative and cannot be maintained absent an underlying tort that is actionable without the conspiracy."
