Conceal

The ability to hide objects, other people, and yourself can be invaluable. Being out of sight and out of mind provides many advantages. Conceal is a relatively simple skill: Conceal rolls are opposed by Spot rolls. Some situations can modify the roll; see the chart below for common examples. A creature or object cannot be concealed in a bare room. There must be nearby objects or structures to hide behind.
