How about a little love for the gnome? (pun intended)

Very fun class. I like the "following fire" power. And it feels very gnomish, e.g. distinct from dwarves, which is hard to accomplish.
Despite my dislike of little people, I might use this. Don't go starting up any halflings though.
Definitely one of my favourite fan-made classes too. I’d love to see it finally finished with a full set of templates as well. 
Thank you for the kind words!
Per RA’s request, the Gnomish Arbalestier now includes templates (scroll down on the link above).
These are my first templates, and I tried to create characters I could have fun with.
Very cool, though I’m surprised the Tunnel Runner has no crossbow or arbalest at all.
