Destiny 2 Hunter BuildThe Rat Kings Trick

Tricksleeves provides a 100% damage buff to sidearms when active, which can then be extended through getting sidearm kills. Using Rat Kings health regen, invisibility and facet of mending (which works with GPG and Transcendence grenade) we are able to offset the low hp requirement by gaining health back rapidly, by either reloading Rat King, dodging to get health back + redirect enemies with Threaded Specter or throwing out grenades which you will have a LOT of. Tricksleeves alone makes Rat King essentially a pocket heavy weapon damage wise and gets even more ridiculous when you consider the high uptime on smoke grenade and the frequency at which you can cast your Tether. This build provides an very active and fast paced playstyle that is extremely fun, but does have a bit of a learning curve as the Tricksleeves activation can be finicky. Once you get everything rolling Rat King can chew its way through GM + level enemies with ease, with the only real downside to this build being its glass cannon nature, with high damage but at the cost of survivability.

Weaponry other than Rat King is purely personal choice, although I personally would not recomend a machine gun or any sort of add clear heavy as Rat King fills that role anyways.
