Oil

 is a hazard element in The Sandbox Evolution.

Summary
This liquid will catch fire if enough heat is applied to it.

Uses
Oil is used to create traps in game worlds, it is most commonly set alight to pose a hazard to the player similar to Lava. Sometimes it is used as a drowning hazard by forcing the player to need to swim through it, like Water, which poses a drowning risk.

Oil is also used as a combustible when it is set alight to heat up other elements.

Oil will trigger a Liquid Sensor, making it useful in creating circuits, advanced traps and machines.

When oil is set alight, it will also trigger a Hot Sensor. Again making it useful in circuits, advanced traps and machines.

How to craft
Trapping organic elements such as trees underground with stone will craft oil (place trees, then drop lots of stone on top so that the trees get buried, then oil is produced underground).

Cost to unlock
1,250 Mana.
