Everbright weapons,
supposedly, follow the same principles as Blueshine items, in that they can have a prefix AND be blueshine/everbright:
This doesn't necessarily rule out that something can be everbright and pure good. Also seems to me that blueshine/everbright is a prefix, not a suffix, as admantine and mithril are both prefixes (as you can have mithral fullplate of fire resistance, for example.)
I would like to get a pure-good everbright bludgeoning weapon, if only to reduce 2 weapons into 1. It wouldn't matter much to me if the weapon was less effective than either weapon at its particular job, just because its rare that rust-monsters or oozes are really a huge problem.
Of course this could change, but I'll burn that bridge when I cross it.
