What is the DPS formula?

woah woah, asking just in case you've checked, but does aran crit and snow charge do this too? i know the hero thing, but this is the first time i've heard of it being due to "displays in range of % buffs"

I'm pretty sure all of the Aran things show up in your range. I've watched my range increase as I've put points in snow charge, as well as when my combo count increases in an increment of 10. It'd also help explain why Arans have such high damage ranges. I don't really know how the game treats crit regarding your range, but it'll change your percent crit chance display on the stats screen in relationship to your combo count and extra crit chance with combo critical.
