It’s a hybrid Hunter/Stalker tree using Fade Away heavily focused on the crit and damage bonuses from the hunter tree while getting some of the regen perks from the stalker tree. By the endgame I will most likely be using the Until You Are Dead and Unblinking Eye augments alongside the Gunslinger Jabber for the additional crit damage.
I’ll probably open up with Furious Attack and Overclocked in the Stalker tree just to get Guerillas in the Mist, because combined with those two skills it sounds like SMGs will be absolutely ridiculous for Fl4k in the early game. I’ll then throw myself head on into the Hunter tree and the second I unlock the capstone skill of 20% crit chance when shot anywhere on the body I will immediately switch to exclusively using Jakobs weaponry, because their inherent crit bonuses combined with Fl4k is going to be insane. And Jakobs has always been my favorite manufacturer in Borderlands so I’m so happy it seems they might get an OP build because they were kind of neglected in BL2.
Endgame playstyle is this: run into an area, find a badass, enter into Fade Away, stand still, and shoot him three times (75% chance it’s gonna be four times with a maxed out Two F4ng). With a Jakobs shotgun or a Maggie, and the insane damage bonuses you’re getting from Fade Away/Unblinking Eye, I don’t think even a badass is going to survive a lot of the time. And what’s more, with Jakob’s crit perk, all of this absolutely ridiculous crit damage is being thrown out at enemies all around the badass, so they’re dying too. That means you’re exiting Fade Away with a bunch of Interplanetary Stalker stacks and the buff from The Most Dangerous Game, both of which are augmented heavily by Big Game - if you kill a badass you literally get FOUR MINUTES of more than 30% extra gun damage and 13% extra crit damage. It’s ludicrous. You just run in while invisible, immediately eliminate the biggest threat, all surrounding trash mobs are liquidated, and you enter the fight with the enemy down their biggest baddy and all the flimsy guys around him while you’re just getting started with all of your insane damage perks, full health, full shields, high movement speed, and constantly regenerating health.
On paper, Fl4k might have the best skill tree I’ve seen in any of the Borderlands games. The potential for both damage and survivability is absolutely ludicrous. He’ll absolutely be one of the best mobbing characters in the history of the series, and there’s really no reason to think his skillset wouldn’t translate to boss fights either. I thought I was dead set on Zane but after seeing the skill tree for Fl4k I’ve got to play him early before they inevitably nerf him hahaha
