<p>move to Mechanics</p> <p><b>New page</b></p><div>An &#039;&#039;&#039;open roll&#039;&#039;&#039; is a roll that, while typically a random integer in the range of 1 to 100, has a 5% chance of adding another 1 to 100 roll or a 5% chance of subtracting the roll. The additional roll could be added again, any number of times, if the subsequent rolls are also 96 or above (or 5 and below, for a &quot;negative&quot; roll). Open rolls are used in [[FORAGE (verb)|foraging]], [[Combat Maneuvers]], and [[Picking Locks]], among a few other systems.<br /> <br /> It is possible to get infinitely high (or low) numbers in an open roll, however, the higher or lower the number, the more rare the odds of that number occurring. A roll above 100 (or below 0), for example, has about a 5% chance of occurring. A roll above 200 (or below -100) has less than a 0.25% chance of occurring, and a roll above 300 (or below -200) has less than a 0.0125% chance of occurring.<br /> <br /> The concept of an open roll originates from when the world of GemStone was a part of the RoleMaster system (See [[ICE age]]).<br /> <br /> [[Category:Mechanics]]</div>
