1 Bar 1 Bang Bow Build - Nightblade PvP - ESO

This build does not require the Pillar of Nirn or Defiler sets but these are in my current build which i use. Other sets that I would recommend might be Shell Splitter and Scavenging Demise. The great thing about this build is the fact you can swap out the 5 piece sets and have fun messing around with different styles. I would always take the Slimecraw helmet and the Oakensoul ring for this as it's simply the idea for which this set up is built and gives you a  great many buffs straight out the gate. Heres the concept of the build in action:

Weapon should have Nirnhoned, Precise or Sharpened depending on preference and 5 set choices

Crit should be no lower than 55%.

Magnum shot can be considered a flex slot.

Always keep merciless resolve up and slam it on an enemy straight after a LA or Lethal Arrow when at 5 stacks.

The opening for this build at mid-close will be Shadowy Disguise/crouch (this is really a pre fight buff to get you a crit proc and the advantage of initiation) - HA - Lethal Arrow - Magnum Shot - LA - Snipe

Opening for long range fights is simply a Lethal Arrow Spam. Edge in close if safe and start to weave LA into the mix (you need to generate resolve this way). Use Magnum shot for a cc,  kill secure or gap maker.

If you get beamed or jumped on and manage to survive then you should keep Disguise up and pot while you 

re-position. Then when safe you can spam vigor if you need topping up to max hp.

Reviving Barrier is a situational skill which you can use whenever you enter 2-4 v X fights or you are getting hounded harshly.

You can also use it when you have no pot or stam for vigor if needed. you can even use it as a great bait tool, instead of healing you can sit at 50% hp with this up and face tank while pumping out your rotation to win the kill.
