Flare (Subnautica)

The Flare is a tool that is crafted using the fabricator.

It allows the player to illuminate dark caves with a stationary light source, thus making it easier for the player to defend himself or to spot resources.

Uses
The Flare can be ignited and thrown by selecting it from the toolbar and pressing RMB. This will cause the player to throw the flare slightly forwards, and then it will sink until it hits something. An active flare will emit a blueish light for about ten minutes.

The player can also pick up a Flare after it has been ignited. The ignited flare does not illuminate anything when in the players hand. If the player selects it again, it will appear without the red protection cap on and it will give off smoke. It can also be reignited and thrown again. The Flare is infinitely reusable.

The Flare will not despawn. Because of this a player can regularly throw a flare when exploring an intricate cave system. If the player needs to leave they can simply follow the trail of flares back to safety.

Since some hazardous creatures are attracted to light sources, such as Bone Sharks, a player can toss a Flare so that it sinks away from the player, thus distracting the creature.
