This is a build for [Zakti Prime] (the regular one is a piece of garbage) that is supposed to be used in conjunction with the helminth ability Marked For Death (MFD). This is an alternative to my Marked For Death Dizzying Rounds Bronco build. So I recommend you take a look at that if you have the [Dizzying Rounds] mod. It doesn't have the same status chance as this, but it does the finisher opener dealio a lot better.

This is not about dealing damage with [Zakti Prime], but rather opening enemies up to finishers (the explosion innately does that), which is amazing for prepping MFD.

Usage Guide

Step 1. Shoot (while aiming) an enemy so the dart actually hits them
Step 2. Use MFD on that enemy
Step 2.5. Wait for the dart to explode (if it hasn't already)
Step 3. Run up and perform a finisher
Step 4. Profit

It is worth noting that you can self-stagger with the dart explosion so just keep that in mind.

Status

This build makes the [Zakti Prime] have an amazing chance to proc (on average) at least 1 of each of the 4 statuses available in 1 shot. There are 2 ways we are going about to proc statuses (assuming all projectiles hit):

1. The darts hitting the enemy:

• Impact: Guaranteed chance + 53.2% chance
• Puncture: 96% chance
• Viral: 97.2% chance
• None: This is impossible (we have over 100% status so there will always be at least 1 status)

2. The 1 second delayed explosion from the darts:

• Gas: 97.9% chance/tick
• Viral: 99.8% chance/tick
• None: This is impossible (we have over 100% status so there will always be at least 1 status)

This equates to a 320% increase to melee damage if you're using [Condition Overload] (which you should be if you're running this set up) on top of the health damage boost from the viral stacks (up to 325% at 10 stacks).

Riven

This can be optimized even further with a riven, but it isn't necessary. If you got a riven (that you don't want to use for a damage build for some reason), I would suggest you replace Lethal Torrent with it. You'll want to get a riven that is maxed out and with these mods:

• +Multishot
• +Status Chance
• -Weapon Recoil (not needed but is nice if you can get it)
• -Impact (try to get it at or above 100%)

This will make your [Zakti] proc the necessary statuses more reliably than normal (for the [Condition Overload] bonus). Since the [Zakti] guarantees an impact proc on the dart hitting the enemy (regardless of our impact damage stat), so it's in our best interest to remove all impact from the weapon so we can proc puncture and viral more reliably.

You can swap viral for magnetic if, for some reason, you're up against heavily shielded corpus enemies that you can't delete in a second.

Mod Choices

[Suppress] is not entirely necessary but it's more of a luxury so you can do your invis thing easier and it's useful to use this on frames like [Ivara] which are sensitive to alarming weapons. An alternative to [Suppress] would be [Reflex Draw] or [Steady Hands].

[Amalgam Barrel Diffusion] is on there because I like to use [Rolling Guard] on my invis frames (and I would only use this on invis frames) so that extra speed is very useful. You can replace this with regular [Barrel Diffusion] if you either don't have the Amalgam one or if you don't really care about the rolling speed boost.

If you don't have [Jugulus Spines] then you can supplement it with a puncture mod of your choosing. It won't be as effective, but it's something.

We don't use Fulmination because it'll end up causing us to self-stagger more when in close quarters.

Arcanes

I've put on Secondary Dexterity for the passive of extra combo duration (overframe doesn't show that passive). An acceptable alternative would be Secondary Merciless for the extra ammo (not like ammo is that much of an issue here). Secondary Deadhead is okay if the recoil is really bad for you.
