Harley Quinn is my preferred character for Suicide Squad KJL. She brings high mobility and packs a punch with her grenade kit. Here traversal skills are great for swinging through Metropolis like another hero from another universe. Here’s my best Harley Quinn build in Suicide Squad: Kill the Justice League.

What’s the Best Harley Quinn Build in Suicide Squad Kill the Justice League?

Harley Quinn is a great run-and-gun option for players. She’s agile and quick to the trigger. With the right kit, you can easily turn her into a powerful player. Below, I’ve broken my best Harley build suggestions into categories, starting with her best weapons, then her best shield, and finally, her best skills and Talents.

Best Harley Quinn Weapons

Your loadout evolves in complexity as you play KJL. While many might argue that an SMG and a pistol are the right fit for Harley, I prefer to use a Pistol and a Heavy Minigun, and have for the entirety of my playthrough. 

Once you master her Grappler, you can utilize her drone with R1 to get the high ground on enemies and shred them with the Minigun, or get off some precision shots with a Pistol. By far, the best loadout I’ve come across is the Black Mask’s Bulletstorm kit. The weapons apply a Black Mask Mark to enemies that will cause an explosion if you mark three enemies at once within 12 seconds. These were available to Deluxe Edition owners, but you can also make them.

When it comes to Harley’s melee weapon, I prefer to utilize Poison Ivy’s Freeze Affliction so that Harley can make her way through a crowd of enemies effortlessly. I recommend crafting new melee weapons at Penguin to get the best possible loadout. You can then customize the affliction by visiting Poison Ivy.

Best Harley Quinn Shield

Harley Quinn isn’t the tank that King Shark is, so you want to choose a Shield augment carefully. I highly recommend Shields that boost Health and Shield Harvest Chance. You can view your shield stats in your loadout. The Amertek Hotwire Shield Mod is a good example. It offers 15% Health, 16% Shield Harvest Chance, and more. If you need some new shields, head to Penguin to craft some more.

Best Harley Quinn Talent Tree Skills and Abilities

The Talent Tree can be daunting. There are three categories to tackle, and they all unlock independently throughout your time playing. If you choose to main Harley, focus on airborne abilities, combos, and grenade damage. If you think you messed up your build, don’t fret, you can edit your skills at any time. Here’s my recommended talent tree path for Harley Quinn.
