WELCOME TO THE BOARD KILLING SPREE!!!!!!!!!!!!! I live in Melbourne Australia and have a freind that lives 10 minutes from em and hes from Woodstock GA. Small world huh???? hehehehehehehe.
If your doing the sewer quest then you wont have a cleric of high enough level to have Greater Restoration. Go find a temple and get some priest to cast it on you. OR buy several scrolls of it. I recommend buying as many as you can because youll need them later in the game ( lots of them ). Ithink if you buy the scrolls of it anyone in the party is capable of using them but im not sure on that part. You might even have to rest afterwards because they character that casts it may become fatigued.
Hope that helps a little
