In my current campaign I'm playing a Bolt Ace Gunslinger, and we just hit level 9 and came across 100k gp. I'm leaning towards just being boring and getting a +3 crossbow and upgrading my cloak of resistance, but there are so many good items hidden away in the myriad of books, I was wondering if anybody had any they could recommend.
Thanks in advance!
For sheer coolness factor, I'm a fan of the Cornerstone Crossbow. It basically lets you fire it like a magical grappling hook with a chain of force that pulls you to whatever solid thing you aimed it at. The Sharpshooter's Blade is also a useful thing to attach to a crossbow in case you get stuck in melee.
The Designating ability on your weapon can also be great if you have a lot of martial characters in your party, especially ones with a lot of attacks.
There's also some cool magic ammo, like Splitting Bolts.
