These figures are an independent-roll estimate: they treat every kill as a separate roll at the listed rate ( 1 − (1 − p)KC). Real drops can involve guaranteed rolls, point/invocation scaling or completion rewards, so the true odds may differ. A probability is never a guarantee — even far above 90%, the drop is never owed to you. Drops without a fixed 1/Nrate show “—”.
