4.9Borderlands 4 Harlowe Class Trait
Harlowe Class Trait in Borderlands 4 is Entanglement. When she uses an Action Skill, affected enemies will be Entangled for a brief period of time. The enemies will exchange both skill damage and gun damage with each other, and with every other Entangled target nearby.
On paper, Entanglement could be considered a minor perk, but in combat, it changes mob and boss fighting strategies entirely. Firing at one enemy distributes damage across the group, so groups of enemies can be shot down with reduced bullet counts. When against one-targeted enemies, Entanglement helps to stack additional radiation and cryo procs so as to deal deadly burst damage.
Borderlands 4 Harlowe Skills
Three powerful Action Skills are part of one of Harlowe’s skill trees in Borderlands 4: Chroma Accelerator, Zero-Point, and Flux Generator. They dictate your playstyle and allow going back and forth between high damage, crowd control, and team support.
Zero-Point (Seize the Day)
Zero-Point locks a target in Stasis for 10s; if an enemy is immune, it takes direct damage instead. Reactivate to slam the frozen target and trigger a small explosion. Base cooldown is 35s, and the slam has a brief 1.5s retrigger timer. This is your reliable hard CC in Borderlands 4, great for isolating elites or stopping a rush.
✏️ Tip: Use Zero-Point to set a clean punish window. Freeze, reload, then re-press to slam when your magazine is ready; you keep control without wasting shots.
Chroma Accelerator (Creative Bursts)
Chroma Accelerator fires an Unstable Energy Pocket that pierces targets and deals Cryo while traveling. You can press the skill again to detonate it for a big Radiation blast. Chroma Accelerator has a 38s cooldown. The pass-through and explosion are the core of Harlowe’s mobbing and boss burst in Borderlands 4.
✏️ Tip: Pair Chroma Accelerator with Neutron Capture later. Stored Action Skill damage moves to your gun as bonus Radiation after you pop the orb, which speeds both clear and single-target phases in Borderlands 4.
Flux Generator (Cosmic Brilliance)
Flux Generator throws a field that deals Cryo DoT, Entangles enemies inside, and grants Overshield to allies who stand in it. Duration is 22s with a 55s cooldown, and you can pick it up and toss it again to reposition the zone mid-fight in Borderlands 4.
✏️ Tip: Drop Flux on a choke to stack Entanglement ticks while your team pockets Overshield. If the fight shifts, scoop the Generator and re-throw to keep pressure where the mobs actually are.
Borderlands 4 Harlowe Skill Trees
Like other vault hunters, Harlowe in Borderlands 4 has three skill trees (Red, Blue, and Green) and, as mentioned above, they are paired with the Action Skills. Thanks to three distinct skill trees, you can lean into burst damage, lock down fights with Stasis, or play a supportive zone-control style with Overshields.
To experience all the benefits and unlock the full set of perks, level up your Specialization or ask our team to do it. On level 100 of the spec, you’ll unleash the full potential of your character.
Seize the Day (Blue Tree)
The blue tree named Seize the Day is built around Zero-Point. This tree freezes one threat, links enemies via Entanglement, and lets you punish while they sit in Stasis. Branches cover controller tools, bruiser sustain, or Radiation chain plays, so you can lock a priority target and swing momentum.
Creative Burst (Red Tree)
Creative Burst tree is the red one, which powers Chroma Accelerator and stacks elemental output. By contributing your skill points to this tree, you get higher Action Skill damage, stronger status effects, and tools to cycle cooldowns faster.
Additionally, you get access to augments like Neutron Capture and Special Purpose Magnets that reshape the orb, and capstones such as Demon Core, Q-Ball, or The Shattering Light flip your endgame flow.
Cosmic Brilliance (Green Tree)
Cosmic Brilliance tree is green, and it revolves around Flux Generator and area control in Borderlands 4. The field deals Cryo DoT, Entangles enemies inside, and grants Overshield to allies who stand in it, with branch options for team anchoring, ricochets, or raw zone damage. You can pick up and re-throw the Generator to keep pressure where the fight moves.
Borderlands 4 Harlowe Augments
Borderlands 4 gives Harlowe a tight set of Augments that reshape how Chroma Accelerator plays. Augments can be found in your skill trees, and you can pick the required ones for a perfect build.
| Augment | Effect |
|---|---|
| Neutron Capture | Chroma Accelerator stores damage; on detonation, part transfers as bonus Radiation to your gun. |
| Special Purpose Magnets | Orb pulls enemies while traveling; detonation deals more damage per target already hit. |
| Field Research | Killing with the orb (or Entangled kills while active) refunds a portion of next cooldown. |
| Containment Breach | On detonation, the orb splits into several smaller, fast-moving orbs. |
| Voidstar | Passing near an enemy removes a chunk of current health and Freezes the target. |
