Currently Infinity - 1 point in each proc rest in Spirit till 150 for the +1 stat then 6 fighting/end for the +1 in those categories.  Afterwards either max out spirit or attack speed.

For Terminal Bounty farming substitute Canadian Devil for Stabby Flip and swap back for the boss.

Rotation is Hold down Bang Boom > Hulk Hand Arrow > Bang Boom Pow > Real Armor Buster > Stabby Flip > Kaboom! > Bodyslide to safe distance, can tap it in the last .5 seconds of Kaboom! animation and as soon as the animation finishes you'll port to safety.  Server Lag on Cooldown- bonus points if you interrupt boss mechanics with it like Jugg charge or Magneto signature.  Blast Bang Bang until the rotation comes off cooldown and do it again.

The nice part about this skill setup is it's very safe if your timing is good, can use Stabby Flip to hop behind boss animations and Bodyslide to dodge otherwise.

Pets stats aren't enabled yet but these are the rolls you'll go for when they are.
