In monster hunter freedom unite what does spirits whim mean

whim is for the breakability of your items that you use except your weapons.

boomerang, bugnet, pickaxe, flute are some examples. look at the status by pressing start. is the whim green? (that means it's activated)
is the whim positive or negatively activated?

positive whim means breakables won't break easily
negative whim means they'll break easily

note: at your home, go to the drawer and read the info magazine about some skills if you're not sure what they do.
searching the net is easier too.
