I read through goblins of golarion and it's absolutely brilliant. A greater shower of eejits you'll never find, so since someone has hinted at a possible evil campaign in the making... Well, who am I to say no?
So, I'll see how lenient the GM is in terms of allowing me run around on the back of a big bloody spider, because I love spiders. I was thinking of also taking the trapper archetype aswell, mostly to get access to stuff that explodes. (Happiness is a naked flame and an unprotected face.)
Finally... I'm just not sure about combat style, it's the one thing that's bugging me. Thinking of it now, I might go with Ranseur and maybe something like agile maneouver for a first feat, and generally start working my way towards constant dirty tricks and such to pull on people. If I do get a chance to take a giant spider as a mount, I could also see about a bag of holding full of hornet's nests. Are something suitably horrid that will really put the shivers up people.
