The point of the grick is simple. At level 3, you're supposed to have 2700 gp of items, and none of it shold be worth more than, mebbe 1400. Of course, I'm betting one or two will have a +1 sword, but, it happens. If not, someone's going to have Magic Weapon.
Think of the encounter, where the party doesn't have magic weapons all over... but has access to them. add in a couple Gricks...
Chaos ensues.
