Do your guns feel weak? Why not try a kill skill zane! Make your guns twice as good!
This build is based around always having kill skills active which buffs fire rate, movement speed, lifesteal, and more. Basically making it a permanent buff.
With this build activating an action skill will activate all kill skills so having a low uptime and fast cool down for action skills is key.
The barrier action skill lasts the same amount of time as your kill skills so when entering combat place your barrier and once its gone activate your SNTNL to always have your kill skills active.
One shot weapons are best for this build due to the kill skill playing dirty. This makes the next 5 shots shoot double unlike the other kill skills which are on a timer.
You will encounter some downtime where no kill skills are active due to the cooldown of the action skills (you can see when and what kill skills are active with the icons at the bottom of the screen). In this time find a place to hide to recharge your shields. This will speed up your action skill recharge rate because of the adrenaline skill. (the barrier takes around 20 seconds to recharge with no shield and 10 with full shield).
Finally the class mod you should use is a legendary class mod - executor. This will give even more kill skills along with buffs to existing kill skills but the build is usable without it.
