re: DnD
@Murkrow no, this is about plain old hand-loaded crossbows, with Crossbow Expert. From looking at forums it's quite unclear if it's viable to dual wield two hand crossbows (if only for extra dmg in the first round, dropping one afterwards) or a crossbow and a dagger (Crossbow Expert lets you shoot with a bonus action)
re: DnD
@Murkrow worst case I'll hold one crossbow and have a backup one holstered as a suprise
