After a breif read-over I have added this to my growing pile of "RC Presents" adventures.... I may use this in my current game, albiet at a higher level. This makes for a nice 'drop in' adventure with minimal fuss.
As always, very nice! This is a nice adventure for low-level pcs.
I noticed you're using 3.0 still (or perhaps a hybrid?).
Where did the gambado stats come from? Is that the version from the Tome of Horrors? (That was a nice use of a weird old monster, by the way... in an area where the pcs are bound to expect it to be undead!)
One question though and please don't be offended but I am curious do you commonly give out equipment such as a +2 ring of protection, +3 poision injecting mace, and a +2 keen ghost touch dagger to 1st level PCs?
Honestly, I refuse to be a slave to weath by level guidelines I'm only curious as that does seem a bit on the rich side.
