About Gunflash Ninja
Ninja OR SLAYER with Amateur Gunslinger (free of prerequisites) from the Grit rogue talent + Mysterious Stranger (probably only 1 level of it). This lets me pick up Quick Clear through Amateur Gunslinger, and I am not required to turn it in for Extra Grit because Amateur Gunslinger came free of prerequisites via the rogue talent.
This does, unfortunately, require an extra 2 feats. Ninja is solid because it has all of the charisma-powered bonuses to it as well (probably only taking 1 level of gunslinger to get guns and all the deeds, plus Cha to damage at level 1). Ninja has the repetitive gun sneak attack powers - turn invisible, shoot gun, turn invisible, shoot gun. Etc. NINJA GUN. :P Perhaps even a rifle rather than the usual pistol. I wonder how much damage I could output? Full attacks will be a must. Improved Precise Shot enables flawless sniping and crazy sneak attack damage - perhaps I'll take a way to get more than 30 foot sneak.
Slayer is good because better BAB and I can also get the mighty Ranger Combat Styles, as well as the excellent "pick your own favored enemy" ability.
