Diamond

Diamond is one of the 8 Infusable gemstones. It can be Infused by reaching a certain height. The exact height is unknown, since scholars disagree; the mountain range next to Tryph and the peaks next to Maentyr are known to be sufficiently high. When Infused, it has a variety of uses:
 * Herblore: clears the liquid, making it transparent, odourless and tasteless.
 * Weapon: causes the weapon to become increasingly transparent the greater the speed it travels by (relative to the bearer), causing blocking and evasion to become more difficult for foes.
 * Shield: makes the shield invisible, only revealing it after being hit.
 * Self-Infusion: grants the sorcerer transparence, or in the case of sufficiently large gemstones, invisibility.
 * Can be touched to an infused Ruby to spend the Diamond's Infusion and make the Ruby shine a white bright light, useful for lanterns.
