Harlowe is undoubtedly a top-tier pick, demonstrating an impressive ability to subdue large groups of foes through her area-of-effect (AoE), control, and healing abilities.

Best skills to choose

Solo

Action Skill: Chroma Accelerator

The most effective ability you should concentrate on is the Chroma Accelerator. Upon activation, this skill creates an unstable energy pocket that travels through opponents, causing Cryo Damage. By pressing your action skill key, the pocket will detonate, inflicting substantial radiation damage.

This essentially acts as a mini nuke and is easily the best move to use when playing solo.

To discover the ability you’re interested in, simply key it in the ‘Skill Filter’. This will help you determine if it’s worth investing in and how many points you should allocate to it.

Co-op

Action Skill: Flux Generator

When hanging out with your friends, the Flux Generator is an outstanding Action Skill you might want to choose. It lets you toss a Flux Generator creating an Energy Field dealing Cryo Damage over time and entangling foes. Simultaneously, allies within this Energy Field receive Overshield protection.

In this scenario, you’ll have command over the battlefield, inflict considerable harm that’s almost unbelievable, and shield your fellow combatants. To me, it seems like a double advantage.

To discover if a particular skill is worth investing in and how much effort you should allocate to it, simply enter your chosen skill within the ‘Filter by Skill’ section.

Working together as a cooperative Harlowe player is much like playing her on your own, except you’re assisting your teammates during battles. The enhanced fire rate, gun damage, and Radiation advantages are all present, but the game also introduces supportive skills such as “Pencils Down” and “Momentum.

Your primary investment leans towards enhancing your combat abilities, with a major focus on boosting Elemental Damage, Radiation, and Irradiation here.

Best Capstone

In simple terms, there’s no debate that the top Capstone is the Demon Core. This is because when you’re focusing on a Radiation build, it’s essential to have the capability to fire Radiation Bolts at your opponents.

Additionally, whenever you engage an adversary through the use of your Action Skill, you will have the ability to instantly radiation them.

Or in a more casual manner:

Not only that, but when you go toe-to-toe with an enemy using your special move, they’ll take some extra damage automatically.

Essentially, this Capstone will make it feel effortless for you to handle even the most challenging supervisors. It’s strongly recommended that you seize the opportunity to get it whenever possible.

Weapon type

By now, it’ll come as no shock to you that Radiation weapons are your best friend for Harlowe.

Instead of prescribing a specific weapon, we suggest selecting one that aligns with your gaming technique, and make sure it inflicts Radiation damage for optimal results.

This entire build is made to capitalize on that damage, so it must be part of your weapon.

How to play Harlowe

If you’re playing Harlowe alone, it would be wise to use your Area of Effect abilities the moment you encounter a challenging fight. Furthermore, make sure to maximize the use of your Entanglement skill whenever possible.

In a solo game with Harlowe, always employ your Area of Effect skills when combat gets tough and prioritize using the Entanglement ability as much as feasible.

As a gamer, I’d say, “Kick off by activating abilities like Confirmative Reality first. Once you’ve ensnared your foes, don’t hesitate to unleash a barrage of attacks. Your skills will trigger faster than bullets from a rapid-fire gun. They’re all designed to complement each other, so you’ll be vaporizing enemies and blowing them up with Dirty Bomb. Just remember to keep your distance, ensnare, attack, and let your abilities do the heavy lifting for you.

In terms of co-op gameplay, the approach remains quite similar. Employ your Area of Effect (AoE) from your Action Skill, boost teammates, and maintain a defensive position. Your Entanglement ability is extremely effective, immobilizing large groups of enemies for you and your comrades to target simultaneously. As in the single-player mode, your skills will continue to activate autonomously.

As a dedicated fan, I’d enthusiastically say that Harlowe, in Borderlands 4, is the character who rules the crowd! She truly shines when surrounded by multiple enemies, excelling at herding them together for an easy takedown. If you smartly leverage Radiation abilities, you can breeze through the game from start to finish without any significant trouble!

In summary, here’s a guide on crafting the ideal Harlowe character for Borderlands 4. As you venture through Kairos, don’t forget to look into obtaining free rewards via Twitch Drops or progressing through all Borderlands titles sequentially.
