This spell inflicts 1d6 Constitution damage and paralyzes the target. A Fortitude save negates both these effects. Those affected by failing their initial save must make another Fortitude saving throw each round to throw off the effects the wasting disease. Failure on these subsequent rounds inflicts another 1d6 Constitution damage as well. This damage stops once the target has succeeded at a Fortitude save or after 1 round per caster level.
Those whose Constitution is reduced to 0 or less by Durlock's Withering Pox become wights. These creatures are not under the control of the caster and can be turned or rebuked as normal.
Material component: A piece of decayed flesh from a wight and a gem worth 500 shillings.
