[@DeadbeatWalking] if you're dualwielding both pistols it'll be impossible to kill the Void Hounds (they're at 9 Defense) as you can't crit them.

Are you attacking with your one-handed peacekeeper pistol or shooting all bullets at the Void Sorceror?

If you're only using your peacekeeper you'll also get bonus shots from your Quickdraw ability.
