The best Harlowe builds in Borderlands 4 take full advantage of the Gravitar's experience as a former Maliwan combat scientist, using her mastery of battlefield manipulation and the elements to great effect. Oddly enough, Harlowe feels the most like the traditional Siren we've come to know, more so than the best Vex builds, despite her reliance on tech.
Nevertheless, the Gravitar brings much more to the table than you'd initially expect, so I'll go over three of the best Harlowe builds at max level below. I'll cover the skills, augments, and capstones to pick, alongside gear that works with them to make this character shine. I'll also go over a strong levelling build to get you started on the Gravitar.
