A bebilith's bite causes a horrible withering and weakening of the flesh, resulting in a hideous melting and foul rotting effect. This catastrophic withering begins on the round the creature is bitten and continues for another 4 rounds thereafter, for 5 rounds of withering in all. Each round the rot persists, the target must succeed on a DC 23 Fortitude save or take 2 points of Constitution damage. If the target makes two consecutive saving throws in a row, the effect is cured. Heal can also halt the rot effect. The save DC is Constitution-based.
