2.5-4% Bonus Critical Chance on Chained Hit. Stacks 5 times.
3-6 Bleed Stacks from Special Attacks.
30-60% Rending on Critical Hit.
4.5-6% Critical Chance for each expended round in your weapon (resets on reload).
The more crit hits you make the more power you get from this build. This usually means the more attackes you make the more crit hits you can potentially hit which will help keep increasing your crit chance. Using Heavy Eviscerator saw special will help on big/tough enemies since hitting bleeding enemies increases crit chance further. Since you should be able to deal with all melee range enemies both big and hordes, revolver for range is highly recommended as it has long range while also having very high damage and crit damage.
