Medic: Medical Drone and Sustain Builds

At a glance

What Medic is for

Sustain is worth the most exactly where it is hardest to get: Hardcore runs, and the no-healing achievement Zero Deaths! — which, read carefully, forbids healing from items or abilities, making the Medic’s passive contribution the interesting question rather than a disqualifier.

Ranks

Every survivor has five ranks, the fifth added in version 1.0 along with two new synergy nodes, two passive improvement nodes, and one passive node that buffs the whole team whenever Medic is in the squad. Ranks 2 through 5 each have an achievement:

The Survival Level each rank requires has never been published by the studio, and is not guessed at here.

Personal mission chain

Medic asks for five missions, each its own achievement, and unlocks repeatable quests afterwards. Every one raises Team Bond, the squad-wide bonus to Cash and Specialization Points.

Trauma → Hemostasis → Inflammation → Proliferation → Remodelling

The mission chain is the four stages of wound healing, in clinical order, starting from trauma.

Patch history worth knowing

A 2025 patch slowed the Medical Drone’s mode switch from 0.25s to 0.75s, deliberately turning it from something you flick between states into a positioning decision. Patch 1.0.0c also eased her first mission, Trauma, from three items required to two.
