Up to +25-40% Strength, as Stamina depletes.
+12-24% Rending on Enemy Weak Spot Hit for 3.5s. Stacks 5 times.

+14-20% Damage on Second, Third and Fourth shots in a Salvo.
After testing this build satisfactorily satisfies as one of the better vet builds I've tried so far. Its strong, does a lot of damage, and is fairly safe to use with decent regen and self-safety from shovel. But stick close to your friends.
I have tweaked this build now that Exhilerating Takedown is fixed.
