Hi.
I had this questions about some time ago, since I saw this weapon.
Is the mercurial long sword considered a Long sword at all ?
I mean I understand that as exotic weapon the apropiate "exotic weapon feat" must be taken in order to use it, but would all other feats afects it as a long sword ( weapon focus ( longsword ), Improved critical (longsword), weapon specialization (longsword), etc ) ?
