Not that I personally disagree or agree with this kind of idea, I just don't see why someone who knows can't just write it out in plain text for all to see. It's obviously a good bonus that can be applied to even horses apparently, but does this bonus continue to stack on such things? does it mean no-lifers can gain an advantage if this does stack?.
Yeah, I'm just beating a dead horse, because we all know the only way we'll ever find out 100% what it does is by someone who knows, i.e a cRPG team member, posting it on here, which probably wont happen as usual.
EDIT: That's a good idea Dach +1, it could very well be!, I'm going to write down my repair costs for items and if I get that message I will track the costs.
