Heal

Heal, also known as Healing, is a terran ability used to heal friendly biological units.

The zerg have the natural ability to regenerate health over time, though the zerg have evolved their own abilities similar to heal, namely Transfusion and Rapid Transfusion, to rapidly regenerate health.

StarCraft

Heal

Medics use this ability to automatically heal friendly biological units in range.

Usage
Hotkey A Cost 1 (per 2 hit points) Range 2

Heal counteracts the stimpack ability, so the use of medics allows the terrans to get the most from stimpacks for marines and even firebats.

All zerg units and structures have the ability to regenerate health over time, though heal does provide excellent support for the zerg.

StarCraft II

Versus

Healing

The medivac dropship heals a friendly biological unit nearby it.

Can be set to autocast. May only be cast on one unit as a time, and may not be stacked by multiple medivacs.

The ability does not "stack" with a roach's fast healing rate.

Medivac dropships cannot heal units inside of them.
