Build - Asari Huntress Infiltrator: The Combo Master

I've yet to see a Huntress build taking advantage of TC rank 6 Bonus Power, which is a shame because not only do you get the most reliable platform for biotic explosions in the game, but it also leads the scoreboard by about 15-20,000 points on average on Gold. Furthermore, I like to think of this as my boss-killer kit, particularly against Reapers. It tears through Brutes/Ravagers/Banshees like nothing else in the game.

THE BUILD

It's 6/6/6/5/3, though within that some elements are up to you.

The first thing you have to keep in mind with this build is that it's not your standard Infiltrator. Normally you'd exploit TC's proportionate cooldown to carry big guns, but in this case you need to use two powers per cloak cycle so cooldown management is crucial.

Tactical Cloak - Duration/Recharge Speed/Power

Strictly speaking, duration is optional. DC's cooldown is low enough (again assuming you're not carrying a Widow or something) that ~5 seconds is enough time to follow up with Warp, but 1-2 seconds leave you with very little margin of error, so if your target, say, goes round a corner or moves away from you, you're screwed. The Damage evolution only adds <200 damage to Warp anyway, so Duration is much safer.

Again, Recharge Speed can be swapped for melee damage, which may be advantageous if you're surrounded by mooks, but IMO it's too situational and considering you're going to be cloaked for a while, probably not worth it.

Dark Channel - Damage/Slow/Pierce

Damage is a no-brainer, DC is for priming combos and will rarely run out its total duration. Slow, again, no-brainer, <3 seconds is more than enough time to pull off a combo in one cloak cycle, and since you'll exit TC with your follow-up Warp, it lets you cover a bit more ground before you're vulnerable to enemy fire. Only thing I might say is if you feel like using rank 4 Damage on TC, shaving off 0.25 seconds will make your margin of error a little wider. Pierce - this is where the boss-killer element comes in. A general damage bonus may be viable but it's nowhere near as useful when your primary targets aren't mooks.

Warp - Detonate/Lasting Damage/Pierce

Detonate for obvious reasons. You have some flexibility with Lasting Damage; I prefer the extra upfront damage but Expose can also be effective. Pierce is obvious, as you'll be using TC's cooldown anyway and both Dark Channel and Warp stripping barriers and armor makes you ridiculous against bosses.

Class Passive - Power Damage & Capacity/Power Damage

Not complicated, you want your cooldowns as low as possible and your primary source of damage is powers.

Fitness

This may be arguable as you'll be spending most of your time cloaked anyway, but I feel like two much of a glass cannon without it. The only reason I might go the other way is that Class Passive rank 6 Heavy Pistol weight reduction will give you 200% cooldown with a Talon without wasting a mod slot with ULM.

Weapons

To an extent, this doesn't actually matter too much because your powers are your "weapons". That being said, if you're forced to deal with something while TC is on cooldown, you need an option. Personally, I find the Talon very effective, and I only have it up to IV. Otherwise, I'd recommend a Paladin, a Carnifex, or an SMG. If you're lucky enough to have a Talon VII-X, you won't need ULM, but otherwise it's too heavy to go without. In terms of other mods, in order of priority, Piercing, High Caliber Barrel, Magazine Upgrade. The primary theme of this build is tearing up armor and barriers, the Talon has an inherent bonus against the latter and Piercing gives it one against the latter.

Gear

I go with Adaptive War Amp, but Commando Package may be better depending depending on your levels for each. Failing that, anything that boosts power damage; recharge reductions are generally pointless.

Playstyle

Not only is this build very effective, it's also very easy.

1. Tactical Cloak
2. Dark Channel
3. Warp
4. Shoot with Talon
5. GOTO 1

Use soft cover, abuse your long TC duration to revive teammates and cap objectives; if you do it just before starting you'll be cloaked the entire time.

The build is by far the most effective against Reapers because it melts through bosses and most of their mooks lack shields. That being said, almost every boss in the game has armor, and biotic explosions, your bread and butter, give you something to use against shielded enemies even if it's a bit weak. This is where a powerful gun like the Talon comes in - a headshot is usually enough to down a mook's shields and the built-in bonus to shields and barriers mean you can still contribute to things like Atlases.

Oh, and if you have it, bring Warp Ammo. Very often you'll be shooting at primed targets and it makes your guy even more beastly against armor.

Constructive criticism appreciated, I hope anyone who tries this build loves it as much as I do!
