For optimal use of keystone while focussing on melee gameplay, kill one enemy with the revolver to keep melee specialist effect up every 10 seconds.
Range weapon choice: Build works with all range weapons, but revolver is king because the fast swap and high crit, working well with this build. The keystone also gives crit chance so you can even consider changing out surgical but I decided to keep it and shoot before reaching max surgical stacks. With a few surgical stacks + keystone you always crit. Due to always prepared when switching to your ranged weapon after a melee kill you always have 1-2 bullets in your revolver, making you ready to quickly headshot elites even when you didnt have time to reload.
Melee weapon choice: You can play this build with any melee weapon. The Antax V is my current favorite but Chainsword comes in as a close second.
Enjoy the build!
