So my Cleric has been tainted and has now 2 points of taint. Looking up the rules I discovered taint can be partially removed by the spell remove disease.
So I guess taint is considered some kind of disease, at least mechanic wise?
One of my Cleric's domains is the Pestilence Domain (Complete Divine, p.141), which grants him the following power:
"Granted Power:Immunity to the effects of all diseases, though clerics with this power can still carry infectious diseases."
Does this mean my Cleric is immune against the effects of taint?
