Yeah, these are the ones we give to newbie wizards. They eat these and gain the mana from it, thus increasing their own. These ones aren't too bad to get, so long as you don't mind fighting darkspawn. They're probably the easiest of any of the magical beings to kill.

[Which. Says something about the farming process. As well as wizard culture as a whole, if they're eating these things.]

What're you gonna use 'em for?
