Actually I'm currently playing a pure ranged rogue and I'm starting to think that the crossbow might possibly the be best ranged weapon (in the reload category anyways). It has the fastest reload speed with very comparable damage to the arbalest because it doesn't suffer any crit damage multiplier or the accuracy penalty from firearms.
I wonder if Bloody Slaughter is worth it - not sure if I need the extra crit if the enemy is gonna die anyway. It'd be helpful for them to state its low Endurance threshold
I'm thinking that since 3 or 10 CON is essentially the same thing in the sense that you get one-shot or something like the previous posters have mentioned, then I might as well go 3 CON. In a way, the best of both worlds are achieved since I can min/max and and with the same practical results from the low CON. Thoughts?
