Golden Axe, Joyeuse, Cinquedia, Terror Bear, Nebula Whip, Nunchakus and Illusion Fist.
(It's currently unknown whether 1) Nebula Whip can still be extended 2) The ability of Cinquedia that makes user to teleport to enemies' back is still intact) if the user is not Morris bloodline/Soma
but it still would be cool given the fact that they were beautiful-yet-deadly weapons holding gorgerous ancient magic or something so probably they would be valuable)
If sub-weapons count then Castlevania X68000 herb, CV2 golden dagger and CV2 laurel would be in the roster
