This creature appears as a statue constructed of rock and crystal. It has almost no neck; its head seems attached firmly to its shoulders, though by observing it, you see that it is able to turn its head freely. Each of its hands has two fingers and two opposable thumbs.
Speed 20 ft.
Chrystones open with color spray which emanates from their mouth like a breath weapon and then close for melee combat if targets are close enough; otherwise, they stand back and fight with their longswords. If a battle is going poorly, a chrystone attempts to retreat and ambush its opponents when it has repaired itself.
When a chrystone is destroyed, it shatters, spraying razor-sharp fragments from its form. Creatures within 5 feet of the chrystone take 2d6 points of damage. A DC 12 Reflex saving throw halves the damage. A chrystone can prevent itself from shattering by making a DC 12 Will save as it is destroyed.
Three times per day, a chrystone can use its stone shape to repair itself, healing 1d6 points of damage per use. This requires a full-round action that provokes attacks of opportunity. The save DC for the chrystone’s color spray includes a +2 racial bonus.
Whenever a character strikes a chrystone with a weapon (magical or nonmagical), the weapon must succeed on a DC 14 Fortitude save or shatter into pieces. A magic weapon uses its own save bonus or that of the wielder, whichever is higher. If the weapon breaks, the chrystone takes no damage from the attack. The save DC is Constitution-based and includes a +2 racial bonus.
