I made this for a friend who wanted to play a gunslinging monk in Skull and Shackles. ...I may also have watched a certain movie too many times... >.>
Anyway, disclaimer is that this is not meant to be exactly equally powerful to standard monk (which I think most people agree is a low bar). This class is probably stronger than a typical monk, at least when it's doing what it's good at. But it should be in the power scale of barbarians or paladins.
I made an archetype similar to this idea awhile back. A lot of these abilities look like needless copy/paste.
Gun Kata isn't just about beating people up with guns while shooting. It's also about making fighting positions that make it difficult for enemies to shoot you. I'm also not a big fan of point blank shot working for within first range increment. Remember that there's ways to increase that increment.
@Cyrad: Yeah, unfortunately there is a lot of necessary copy/paste. For example, Gun Kata works very similar to Flurry of Blows... but not exactly. So I have to replicate a lot of the text to make it clear which parts are the same and which are different. I could probably rewrite it to be shorter, but I worry it would be less clear. Honestly, this archetype changes so much I should probably just declare it an alternate class instead of an archetype.
I definitely cared more about fulfilling the core concept I envisioned for the class - versatile, short-range firearm combat - then I did about making reference to the movie. This class is inspired by the grammaton clerics, but it's not meant to be an exact reference.
Point blank shot could get wonky if you were a mythic equalizer and took limitless range, yeah. But in that case you are running an mythic campaign and all balance bets are off. Not sure there are any other ways to really break it, though. With regular pistols your range is shorter than usual point blank - only 20 ft. - and even a distance firearm only gets you 10ft. past typical point blank range.
I think it's more important to simplify bookkeeping; I didn't want the player to have to remember "Am I in point-blank range? What about touch AC range? Which one lets me use my trick shots again?" So I just made them line up.
@Adam: I actually have a PC playing a Cryptic in my current Way of the Wicked campaign. His Stealth score is +40, but so far that's the only way he's really broken anything. :) Didn't notice that archetype, though, that's cool.
