Guess that mob Version 2.

I liked making this rhyme and made it a lot harder.
But yeah veteran maplers here should guess it quickly right?
here goes.

4th monsters:

First hint:
I used to be hunted, for something I posses.
I mean, more monsters here have it but I have to confess....
I'm the weakest around and less annoying to kill.
And they tend to hate my older brothers because of their skill.
And now you probably wonder what could this possibly be?
A lot of monsters drop something valuable as far as I can see...
Well this thing I posses, is different in one great way.
Hmm.. a pass to a yet to happen place is what you could say.
