===EXTRAORDINARY EFFORT===
Extra effort and hero points allow characters to accomplish a lot. However, there are those times when even extra effort isn't enough and extraordinary effort is called for. In these cases, you may wish to use the following option.  Once per adventure (more or less at the GM's discretion) a player can decide to use extraordinary effort. The player may spend any or all of the remaining hero points as well as up to three fatigue results (which renders a normal character unconscious). These can apply to any of their normal uses, and the benefits stack. So a hero who uses extraordinary effort, expending three hero points and suffering two fatigue results, can apply five levels of extra effort to a task. The player cannot spend hero points (if there are any remaining) to offset the fatigue from extraordinary effort.
