Is there any documentation for the plugin feature of Shoddy? I wouldn't even know where to theoretically begin.
Oh, and is Acupressure supposed to bypass the evasion clause? I mean, it would kind of have to in order to not suck (it sharply raises one of six random stats on use, one of which being evasion), so if when it got the evasion boost it just said "but it failed!" it would nerf a perfectly fine move. It'd be fine if it were changed so that it were just one out of five random stats, modifying it so it doesn't use evasion, but that would be kind of changing the rules. I guess it could be a clause or something?
