I am currently playing a Black Jack/Assassin build. It is very satisfying in combat and my character Rosario has twice as many kills as everyone in the group..all 8 slots have filled with unique weapons. One of my favorite pistols is Eccea's Arcane Blaster. This pistol has a chance to dish out 1-3 bullets and can score knockback. Paired with Thundercrack Pistol that has a storm rune. That storm rune can wipe out groups of people easy. Then quick switch through blunderbusses mercs.
