I'm hoping for a Bat Computer. Wouldn't that be cool?
But, on the topic of loot, Pisca could use the Ring of Protection if she's going to continue to perform the role of shield in combats. Pisca, as a bard, has no option for defensive spells. But, then again, we've all been attacked at one time or another.
What might ultimately be the best option for this sort of gnome-as-shield tactic, would be a wand of Mage Armor. Pisca's coming up on a time at which the chances of UMD success are pretty good.
Another tactical possibility I'm going to pursue is the Dervish Dance feat.
