Chemicals

Versioning - Up-to-date Current game version: 0.10.6.2

See also: Medical Items

Chemicals are comprised of different compounds and substances both helpful and harmful, that the crew can craft at a Medical Fabricator, buy, loot, or deconstruct from certain Plants.

Most chemicals come in a syringe, which allows the chemicals to be used without the Health GUI. By holding the "Aim" keybind (Right Mouse Button by default) and pressing the "Shoot" keybind (Left Mouse Button by default). The player's character will swing the syringe and inject its effects to anything it hits, both Creatures and players.

The Syringe Gun can also be used if a chemical needs to be injected from a distance. However, regardless of the user's Medical skill, the "unskilled" effects (red values below) will be applied when using the Syringe Gun, and use the entire syringe in one shot. There are a few exceptions (purple values below).

Some more basic chemicals aren't injectable and must be used through the Health GUI, pressing the "Health" keybind (H by default) on a player or themselves opens the Health GUI. Then any chemical can be drag and dropped onto a limb or the drop circle.

List of Chemicals

The values below represent affliction strength reduction, not to be mistaken with a vitality restoration. Reducing an affliction's strength by any given amount using chemicals may not translate into that amount being restored to the character's vitality.
An affliction's strength and its effect on vitality are two interdependent values in Barotrauma, and the latter may be scaled to vitality: as such, for example, reducing Internal Damage strength by 24 - using Opium, successfully - will effectively restore 20 vitality to a Captain (whose maximum Vitality is 80), 22.5 Vitality to an Engineer (whose maximum Vitality is 90) and 25 Vitality to a Security Officer (whose maximum Vitality is 100). In all cases, the Opium's effect is a raw affliction strength reduction of 24: -4 per second for 6 seconds.
