*Disease: a very real problem in the pit is the spread of disease in the pit. As per DMG.
-Pitmadness: (see Pitmad) caused by a parasite that coils around the brain stem of the infected host. The hosts intelligence , charisma and Wisdom are reduced by 10 each when infected plus an additional one for each day infected , if this reduces any one of the attributes below zero the host can only stagger around howling and attacking anything in site. If all three of the effected stats are reduced to below zero , the pit maddened host is effectively destroyed and killed, and is now just a walking husk. A cure disease spell will cause the infected host to vomit forth the parasite dealing 1d4 damage constitution damageto the host.
