It says in the kit that Beastermasters can't use metal weapons. It don't say nuthin' about them not being able to wear metal armor, but when my new Beastie Boy tried to wear scalemail or chainmail, it was no dice.

Is this a bug, or are BMs in fact unable to wear metal armor. Arrrrgh if they can't! Where's my elven chainmail Jaheira!!

Seems strange, considering Druids (one with nature etc) can use scimitars. I think this is an oversight in the manual.
