One Bar BowBlade using Oakensoul - Nightblade Construye PvE - ESO

This is a pretty simple build. You literally just run through your rotation which will give you a combination of direct, single target damage as well as some AoE damage. Your healing comes from Draining Shot and Relentless Focus (or Merciless Resolve, if you want more healing) so make sure to use the rotation as the first four skills will set up Relentless Focus.

The Ultimate is a bit of a your choice situation. I've used Toxic Barrage and Incapacitating Strike. Both are good (and get a boost from the Ardent Flame passives) but you could use the Aedric Spear or Ardent Flame Ults.
