World of Sharr
Destiny is a mechanical representation of the great impact on the world a character is fated to make. In-game this means that it can be used by the player, and at the GM’s discretion, to directly affect the story in some way. This may be as simple as having a blow that would normally kill the player leave him alive instead – albeit in a critical condition – or it may be something esoteric such as the player deciding that they want a random NPC to become someone import somewhere down the line. Of course, the latter example is possible of devolving into such statements as “I want the barkeep to have a club foot!” If there is no good reason to deny such a request, such as it’s very important that the barkeep be able to run quickly later on, feel free to allow it.
As for increasing one’s Destiny and regaining lost points in the total, the cost is equal to 10 + the new value or the GM may give a point freely at any time. Destiny has the potential to be very powerful and as such the costs of its use is high. As well, GMs should be wary with being overly generous with dolling them out. However, GMs are encouraged to be somewhat lenient with giving players back Destiny points spent on making the game more interesting or cinematic.
