In our Rogue Trader game, my Missionary has become the group's bard. Quite literally. He has a guitar, high fellowship, perform (musician), and spends time writing songs about the exploits of the band. He has taken to abandoning his old shotgun in favor of carrying his guitar into combat.
In keeping with the "no idea is too crazy" feel of the game, I've decided I would like to try to get the guitar modified to act as a weapon in some way. My first thought was to have it modified to act as a sonic grenade type weapon, but I'm not decided.
However, I thought I'd see if y'all had any ideas?
