Oh so it isn't just a preview bug? Thought the effects just looked wonky on the preview (I didn't actually buy it), but that's lame. Even worse than the staff is perhaps the sword... which has the glowy orb just stuck onto the blade randomly? Surely it would have made more sense to have it around the handle/grip? Rather than sticking a globe on the lower third of a blade's edge for some reason?
The other weapons have sort of sensible orb placement (like around the hammer head, around the bow's joints), or even an alternative effect (lightning on the shield) where the orb wouldn't have fit very well. But the sword and the staff... lol.
