Those numbers are from Aggressive Teleportation mod, boosted by debuff mods and primarily by Trespasser set bonus (more damage per enemies caught by any deception skill). This is an overkill so no need to worry if you don't have the legendary set yet. This guide is built around comfortable playstyle.

With the last node on Harbinger tree, activating any of these skills will also grant you a good amount of shield, making it possible to have your shield up 100% of the time.

Using this build, the effectiveness of Borrowed Time is extended by using Aggressive Teleportation armor mod.

Also, Time Rift + Slow Trap = More airtime for enemies. It allows Time Rift to finish its cooldown even before they get back on their feet, and I'm talking about elites and human-altereds here, including Moloch, poor guy spends most of the fight floating in the air.

Note that you can't stack Time Rift on a target that's still floating, so wait until they finish the floating animation and get back up before recasting it. Even so, this combo feels like a cheese and I won't be surprised if the dev patches it later.

And make sure to use Dancing Up A Storm emote while enemies are airborne for more morale damage.

Core


Aggressive Teleportation is one of your main sources of damage, alongside weapon mods.

Pain Transfer and Long Range extend those damages, very effectively. You will deal a lot of indirect damage with these. When you managed to catch a bunch of mobs with Time Rift, just focus on one of them (preferably an Elite) and the small mobs will die in a blink, while other Elites get seriously hurt when the initial Time Rift expires or when your main target dies. Comfortable.

Essential

Slot these in whenever possible.


Also:

• Geiger's Wave: (Time Rift) Every enemy affected by the wave receives Vulnerable status.

Good to Have

• Trample The Weak: Deal 10% more damage against enemies afflicted by Weakness.
  
• A Little Bit Of Pain: (Time Rift) Using the skill deals [60% of Anomaly Power] damage over 6 seconds to affected targets.
  
• Thunder Dome: (Slow Trap) Receive 100% Shield when the skill ends.
  
• Weakening Zone: (Slow Trap) Enemies entering the sphere are afflicted with Weakness.

Aim for Cooldown Reduction attribute on every pieces. This is my current personal setup. The legendary armor set bonus is not mandatory, but very welcome indeed. And I'll probably switch out Short-Term Loan with Geiger's Wave, since cooldown is already pretty fast.

Primary


You will deal low Weapon Damage, but it doesn't matter when you have these mods slotted in.

Secondary and Sidearm


Can be anything you like.

Your main sources of direct damage are your Weapon Mods and Aggressive Teleportation. No need to worry about Firepower, as long as you're using level scaled damage mods. No need to worry about dying. You can use one of your skills to instantly gain shields, on top of already being very tanky.

• vs. Elites: Shoot + Keep them airborne with Time Rift + Slow Trap combo (they'll barely touch you, even those Human Altereds) + spam Borrowed Time (Aggressive Teleportation).
  
• vs. Purple Elites/Boss: Shoot + Borrowed Time (Aggressive Teleportation).
  
• vs. Yagak's Anomaly Rifts: Borrowed Time (Aggressive Teleportation). 1 hit.
  
• Small mobs and flying things: Irrelevant.

A stupid recording i made a few days ago while trying to optimize this build (bad quality and probably not very helpful):


Happy hunting.
