A German-speaking friend of mine (who actually does professional translation) tells us that the in-game items are a "Knight's (?) Portable Camp," which, "receives your tired soul and heals your wounds between battles." And the other is the "Guards of the Amber Ring," or at least a ring of some kind, that "improves your attributes" and casts a spell called "Touch of Earth," which we're told adds a chance to hit. Sounds pretty cool, though there's no information on when the preorder will be available, or even if it will be in America (the box is obviously labeled for Europe).
Any of this entice you to jump in on Warhammer, or were you already convinced? The collector's edition stuff doesn't sound too exciting, but jumping into the beta and the live game is definitely worth a preorder, if you ask us.
