How would a Gnome Sage Sorcerer work? Gnomes have high INT and CON but low STR, but STR is kind of a dump stat for Sorcerer anyways. The INT based bloodline plays towards the gnome's strong points, and Breadth of Experience would make the gnome the party brainiac while still having some useful 0-level spells to use once the 1-level spells are depleted.
I have a Level 1 Gnome Bard, and I enjoy being the party nerd/skill monkey, but once I'm out of rounds of bardic performance I am pretty much useless!
