Modifiers are divided into number modifiers and symbol modifiers. Number modifiers modify your attribute by its value until the task ends, while symbol modifiers have special effects.

Modifiers are revealed from the Grid to modify your attribute. See: Reveal Modifier.

If you treat a modifier as a different modifier, that conversion is final. Other effects cannot treat it again as a different modifier.

Example: If a regular [-1] Skull modifier is treated as the Epic Fail, it then cannot be treated as a regular [+1] Skull modifier by the Tool »Friends in Low Places«.

Modifiers are finite game components. In the rare case that an effect instructs you to find a specific modifier in the supply, but there is no longer such a modifier in the supply, ignore the effect.
