The most fun and hard hitting [Ivara] build I've found.

Gameplay: While prowl'n about, sleep a group (use alt fire), line up headshot, bang! everything in 13m is dead. rinse and repeat

Why those stats?:

• Duration 77%
  A 7.7 second sleep duration is more than enough to line up your head shot get that sweet explosion.

• Efficiency 175% (note I'm using under ranked fleeting expertise and streamline to save some capacity)
  You should be in prowl 24/7 and will be using your artemis bow and sleep arrow a lot and will need this capped out.

• Range 190%
  Needed to get that sweet s 13m explosion from concentrated arrow.

• Strength 154% (204% with Energy conversion)
  You will be doing so much damage that this doesn't really need to be much higher.

Some Notes:

• Kit gun with pax bolt is recommended

• Try using an uncharged shots at the beginning of the mission, this build does so much damage, only using uncharged shots might be all you need for the whole mission.

• I am almost always the top damage dealer while using this build by a LARGE margin.

• I'm using Energy conversion since you only need to cast Artemis bow once and the strength bonus will last the whole time it's up.

• Use whatever arcane you prefer but Arcane energize will help keep you in prowl 24/7
