Can you fire a wrist mounted weapon as a offhand shot while using a 2h weapon in close combat? The offhand shot would obviously be modified by -10, but I would imagine that since both hands are still firmly on the weapon, it would not take that penalty?
Also, Eviscerators do not have Tearing? Seems strange for a chain weapon.
Ah nevermind, just looked at the Errata and see that an Eviscerator is 1D10+10 with Tearing now.
