DT, concerning our recent combat...
Just so you know, Silas' primary method of attacking is with his staff. He's most comfortable using it as he's had one in hand nearly all his life. And he's more skilled with it than his crossbow despite having a little army training in the use of the crossbow (which mainly shows in his Rapid Reload feat). His crossbow is a distance weapon only. Anytime there is the possibility that melee combat will engulf him he'll be using his quarterstaff. If he's got a couple of rounds and some cover then he'll resort to plinking at the enemy with his crossbow.
