      Yes requires reaching the cumulative minimum while it remains possible; preserve the needed spendable spice.
      No forbids reaching that minimum during the rest of this turn. Smaller payments to the named recipient add together.
      Prior payments, gifts and ally aid do not count.
    </p>
    <p className="fine">
      The sender pays immediately. The recipient collects the payment at the start of Mentat Pause.
      Payments made during Mentat Pause wait until the start of next turn&apos;s Mentat Pause.
      Ordinary bribes can be paid out of turn when the current bribe controls permit them; original timing and payment rules still apply.
