Nurse Harrow Is the Sixth Hero in the City Never Sleeps Update

Nurse Harrow is among the six new Deadlock heroes that are joining the roster with the City Never Sleeps Update.

She was the sixth and final hero to be voted for and was released on October 20th, 2026.

"It's hard to know if that chill in the air is from the approaching fall breeze, or from the withering glare of Nurse Harrow, who now joins us on the streets of Manhattan. To some, her practices may seem unorthodox, her patients at the Marble Hill Possession Ward cannot say that the results aren't effective. With Leech Therapy, she throws a jar full of leeches that attach to oncoming enemies, draining their health and energy, before crawling back to deliver their haul. Cracking open one of her vials, she releases her Wretched Vapors, possessing her allies with a powerful boost of effectiveness - though subjects should be warned of the side effects when the vapors wear off. To efficiently keep her teammates fighting their best, she loads her syringe full of Healing Needles to inject medicine directly into their veins. And when her patience runs out, she opens her bag to release all the Lurking Terrors captured inside, making her adversaries run for cover. - "Trust me, I know best.""

Deadlock Nurse Harrow Overview

Lore

A respected pillar at the Marble Hill Possession Ward, Nurse Harrow has dedicated her life to combating the horrors of supernatural possession. A blend of care, severity, and detached pragmatism; Harrow has been called a saint by some of her patients, and a cruel governess by others. Both are probably true.

But while any sane person would question how and why Harrow keeps the pain of her patients stored in her medical bag, none can question the results of her treatment program... cruel though it may be.

Throw a jar of leeches that attach to enemies, dealing spirit damage over time and eating away at the duration of enemy buffs.

Upon landing, the leeches are collectible for about 8 seconds before they disappear. Keep this in mind to optimize your timing and maximize your stacks.

Wretched Vapors (2)
Crack open a vial to release an ethereal vapor onto yourself or an ally that causes a rush, then a crash. Specter Rush: While it lasts, increases the speed of all actions and temporarily numbs all incoming damage creating looming specters. Specter Crash: When the vapors wear off, all actions are slower and any remaining specters deal their delayed damage plus extra damage. Incoming healing will prioritize removing specters first, preventing them from dealing damage.
