Is increased crit like Straight Shot and Internal Release

1. A multiplier of CHR stat?
2. A multiplier of Crit Chance % derived stat?
3. An additive to Crit Chance % derived stat?
4. Something else?

Also ty for all the data, the damage module should be completed shortly. Bad news is I have a lot of meetings tomorrow, so probably won't get any work done on it until Friday. Other bad news is, if diff classes have diff formulas I'm going to have to rewrite some engine code.
