The Crackshot build

Playstyle:
Rack up headshot kills while ADS to dramatically increase the damage output with each kill, potentially one-tapping any low tier enemies that have a head.

A must have:
Consider combining as many Vigilante mods for the extra 20-30% chance to enhance Critical Hits from Primary Weapons.
(I personally use an extra set of 3 additional Vigilante mods on my Carrier's weapon -Vigilante Fervor, -Vigilante Armaments and -Vigilante Offense. Setting the extra Crits to 20%).
(Also using an extra -Vigilante Vigor on my Warframe but it's not necessary setting the total extra Crits to 25%).

Cons:
Enemies that don't have heads should be engaged after you've already racked up damage from other enemies with a weakspot/head for the optimal damage output.

The current build I'm using, made specifically with the Karak Visicron Riven mod in mind. (but anything similar works - try getting a DMG+CC, DMG+CD or all three would be ideal).
Hunter Munitions for the lazy point and click strat (If you've tagged the targets halfway - they'll probably bleed out anyways).

It's my first build I've tried to minmax for a long time so if you got any comments or tips - let me know on how the build could be improved.
