i've a misc and actived it
but i don't know what is it for !?

hmmm. What do you mean by misc? Is it an item, oh if you are talking about a "set"

How do I use them?
which is used for sorting out items.. then you have to add something to it. For example if you have a few items such as orc force, orc relax, select them and click "add to set misc" then when its added activare the set to apply it.

Its basiclly nothing without items in it.

How did i get it? If i Don't know what it is.

Perhaps if you brought something from someone, they sent you the items in a set, or maybe they sent you the set by mistake. If you are asking me

that why would they send you a set even BY MISTAKE, then its simple ; its very cheap.

i mean this

They're collectors items.

Get enough of them & you get an achievement.
(there's one for each type of cucumber)

Also yay!

what will happen if i had 2 miscs !?!

Nothing, they don't actually do anything. They just sit in your inventory, they are mainly for richfags who have too much TC for their own good.

Some of them, e.g. cucumber and pickled cucumber give achievements, but you have to own 100.
