(Haven't had time to catch up and read thorugh everything yet, so just gonna search a place at random.)

I'll buy and consume another Starf Berry from Friend in Need Pharmacy in Silverlight Shopping Mall to restore my Purity, then deposit everything in my inventory that's not equipped, including all my money.
After that's done, I'll search (24) Northpoint Furniture Store (ABANDONED) (By ripping the roof off to see what's in there :P)
