Remove the Over My Dead Body edge; it was mostly created as a joke. It's an incredibly niche occurrence that would rarely use use (well, unless your party frequently has near deaths...)
Tweak Got Your Back edge to say it adds to melee damage too
Add in new edge Herd Fighting that expands on the Got Your Back edge damage
Tweak Beat Back and Nature's Fury to state that pushing an opponent into a solid object leads to being Shaken, with this potentially causing a Wound)
Add in section on Guns in the Gear section. Hey, let's face it: at some point, somebody's gonna ask for one. That said, official MLP:SA policy is that guns do not exist. But if somebody really really really wants one, there's way to make it mostly pony-friendly. ;D
Change flavor text for Clipped Wings hindrance on a good perspective from Page Turner. Thanks!
