Build Overview

Yes, you read that correctly, a Melee Harlowe Build that 1 taps Bosses on UVHM 5. This build is VERY VERY gear dependent but is truly some of the most FUN I have had with my 150+ hours playing Harlowe!

Using Nuclear Winter to boost our overall damage because of its scaling behaviors with Action Skill Damage helps make this build possible. But the bread and butter is Bear Arms and Groundbreaker allowing us to store damage in a small window and give it to our melee for awesome 1 tap kills on bosses!

Potential Transference is something that I thought would never be useful but I was SO VERY wrong haha, on top of constant over shield and healing, this ability allows us to relocate our generator 3 times with no range limit *meaning* we can move it around during a boss fight as much as we wish and even during a boss fight (looking at you time keeper SIT STILL)
