Up to 25-40% Strength, as Stamina depletes.
Up to 5-20% Strength based on the charge time of your heavy attacks. Stacks 3 times.
1-4 Burn Stack(s) on Critical Hit to a maximum of 3-12 Stack(s).
3.5-5% Critical Chance on Weak Spot Hit until your next Critical Hit. Stacks 5 times.
This is kind of a meme build but its working alright for me.
The whole idea is trying to abuse deadshot with the high rate of fire weapon, infernus makes criticals deadlier, headhunter increases crit chance. Stamina regen to get you shooting again, combat ability regeneration so that youll never "go blind".
I chose the axe because the vld clears hordes pretty well, and its can dispatch of single targets quickly.
The grenade perk is to good to pass up although i do consider the ranged damage perk prettyy good.
Also this build makes you practice patience and taking your time, because you want to save your stamina for crits or big smacks
