Non-killer of men. Or the non lethal rogue

[Zomburs]

Im in the middle of a campaign and my rogue is taking the stint of being a non lethal dealing rogue when the opportunity rears its head. Its nice to be able to interrogate the victims. I have taken sap adept and mastery and I am currently lvl 7. I also have a few ranged skills to help me not lose all my hit points as I dont have many. Are there any feats weapons ect I should be looking towards?

The perennial recommendation, of course, is to pair Enforcer with Shatter Defenses to keep the bonus damage from Sap Master going every round.

having the scout archetypes helps, but it's probably too late for that.

also be careful, if someone got twice his max hp in nonlethal damage, they die anyway.
Also guns are bludgeoning and target touch AC, always nice for surprise round.
