For the regular pvm player I figure an Arachnid Slayer is no different than a Spider Slayer -- useful for Dreads. But the champers need it a lot more. What you price it at? What do you price the normal supers at? Problem with lrc books is that, if you need the lrc then you're going to need a set of lrc. But still could be useful for those who carry a Clainin's already.
