Will be prettied later.
Sapphire - offers the CS the gift of empathy. Strength of empathy is dependent on the CS's Magic stat, but the ability to properly use the empathy is dependent on Wisdom. If both are maxed (100 each), the CS begins to understand thoughts as well as emotions.
Emerald - offers the CS the gift of healing others and him/herself. Strength of healing is dependent on the CS's Magic stat and Wisdom stat combined. If both are maxed (100 each), the CS may be capable, with proper work, of bringing back the newly dead. (See below.)
Moonstone - allows the CS glimpses into the future. The distance into the future is dependent on the Magic stat, and the strength of the visions is dependent on the Intelligence stat. If both are maxed (100 each), the CS is able to predict all outcomes for each action he or she may take, but be warned - without a maxed (100) Wisdom stat, this knowledge will quickly drive him or her mad.
Topaz - offers the CS some protection from magic. The strength of this protection is dependent on the CS's Strength stat, and the ability to use the energy absorbed is dependent on the Intelligence stat. If both are maxed (100 each), the CS may go on a quest to gain Full Magic Absorbtion.
Ruby - strengthens each appropriate spell cast with the element of fire. The level of fire infusion into each spell is dependent on the Charisma stat, while the ability to control the fire element of each spell is dependent on Strength. If both are maxed (100 each), then the CS gains the ability to shape existing fire. And with some work, the CS may gain the further ability to create fire.
Quartz - offers the CS the gift of shapeshifting. While the CS may shift into any shape at all, the success of each transformation is dependent on the CS's Agility stat, and the duration of time the CS is able to remain in the form is dependent on Strength. If both are maxed, the CS may, with proper work, gain the ability to transform only part of him/herself into another shape that can be separated from the rest of him or her.
More information coming.
