7.5-15% Weak Spot Damage. Weakspot Kills also ignore Enemy Hit Mass.
5-8% toughness on Chained Hit.
Your Grenades stick to Ogryns and Monstrosities. 6-15% Damage vs Ogryns and Monstrosities
5-8% Strength for every shot fired during continuous fire. Stacks 5 times.
I am obsessed with this build. It's basically an unkillable moving panic button. You have close to 200 toughness with 30 % damage reduction to toughness and a further 25% flat damage reduction thanks to the keystone.
Stay with your team, protect the lil ones, fight with your shovel. Spam lights will kill hordes and patrols reasonably fast. Special heavy attack will OS mutties and most other priority targets.
Meet a crusher patrol, a boss, team starts being overrun ? Swap to your grenade launcher, fire your first grenade, press F and start covering the map with more grenades at a ridiculous rate.
Or just throw your big frag grenade and reset the situation.
This build works best with a scavenger vet to help you regen ammo, otherwise, simply pay attention and use your ammo only when you have to.
