Sacred Haven of Debauchery

It's strange that Viscount, wielding a crossbow, can kill a golem 100% of the time. Revan, wasn't it implied that only one weapon type was meant? After all, Vis has different weapon categories: regular, ranged, silver... it's unlikely that anyone would have three or two types at once, as that would make some situations pointless. But it's a different matter if artifacts are hard to find and match.
