DragonRaid uses ten-sided and eight-sided dice, but refers to them as “StarLots” and “Shadow Stones,” respectively. This is their story:
At the time of The Great Rescue, when the OverLord of Many Names returned from destruction to raise the protective Peaks of the New Beginning, viscious dragons of the Legion attempted to fly over the erupting, upheaving mountains. Raging fire came from their terrible mouths. But as they flew higher and the air grew colder, freezing the dragons' breath in mid-air, a remarkable thing happened. The flames crystallized and plummeted to the bottom of the steep gorges.The StarLots that come with the game are translucent. With regard to “the star encased in the center,” the rules state, “You will clearly see this star if you hold the StarLot up to the light and look through it end-to-end.” Despite what the foregoing story suggests, StarLots and Shadow Stones do not have an in-game presence. In terms of game mechanics, “The StarLot is the crystal used primarily by good forces to shape characters or decide outcomes; the Shadow Stone is used by evil forces for their random determinations.” Incidentally, the Shadow Stone is also used for dragon slaves, humans who are the victims of evil.
Soon after the Great Rescue, the OverLord began to send His people, the TwiceBorn, into the Dragon Lands. On the northern side of the Peaks of the New Beginning, LightRaiders found the wonderful crystals of many colors. Each gem had ten sides, with a star encased in the center (recognized to be the OverLord's own birthmark). Naming them StarLots, they collected them for the use of the TwiceBorn.
It did not take long to discover the power that lay within. And since that time, the StarLots have been used to help LightRaiders survive in the Dragon Lands and raid the serpents' strongholds.
From time to time, StarLots have also come into the hands of dark creatures and dragon slaves. But once touched by those with uncovered evil, the lovely StarLots turn into dark-colored, eightfaceted Shadow Stones – and the star within disappears.
Actually, use of the StarLot is not reserved exclusively for LightRaiders. All weapons do 1 – 5 or 1 – 10 points of damage, regardless of who wields them.
When creating characters, players use a StarLot to generate Ability Ratings for Character Abilities (or Character Strengths as they are sometimes called). These Character Abilities form the foundation of every LightRaider.
In combat, when a LightRaider attempts to strike an opponent, the result of a StarLot roll is added to the character's Weapon Ability. If this amount is greater than the sum of the opponent's Battle Ability and the result of a Shadow Stone roll, then the LightRaider is successful. Likewise, when an opponent attempts to hit a LightRaider, the result of a Shadow Stone roll is added to Battle Ability. However, for the LightRaider, the result of a StarLot roll is added to the character's 'Shield of Faith' value. If the opponent's amount exceeds the LightRaider's, then the opponent hits. As is evident, player characters get a slight advantage against opponents of equivalent ability.
StarLots are also used as percentile dice for “Success or Ability” checks. A 'Success Grid' (printed in the rule books and on the character sheets) indexes Ability Rating (y-axis) against Difficulty Level (x-axis). The intersection of Ability Rating and Difficulty Level provides a number that must be equalled or exceeded on the dice. There are ten percentiles between Difficulty Levels and five percentiles between Ability Ratings. For instance, the intersection of Ability Rating 6 and Difficulty Level 5 is 60. For the same Ability Rating, Difficulty Level 4 is 50. For Ability Rating 7 and Difficulty Level 5, the number is 55. Ten is the lowest number presented in the grid and 95 the highest. For Ability Rating 2 or less, a Difficulty Level of 7 (or more) is impossible to overcome. Similarly, for Ability Rating 2 or less, a Difficulty Level of 10 the highest level cannot be attempted by any Ability Rating less than 9. Unfortunately, the rules do not provide advice on how to determine Difficulty Levels. We have but one example: A character hears a noise and tries to determine what caused it – either a chipmunk, a bear, or an orc. The Adventure Master says that “the noise has a Difficulty Level of 4.”
By the way, no other mention is made of the OverLord's birthmark.
