Artifacts

Kraken's Crown Worn by Emperor Celsus "The Kraken", who played a major role in the reunification of Baz during the Warring Emperors period of the late third century UBC (seven to eight hundred years ago). Though Celsus did not survive to see Baz whole again, his reign as a conqueror and queller of rebellion set the stage for his son, and it is he who is largely given the credit. The crown must be worn continuously for 8 hours before granting any benefit.
 * +2 Charisma
 * The wearer may cast prayer at will caster level 13th.
 * +4 Competence bonus on Intimidate and Diplomacy checks.
 * 3/day wearer may cast true strike on self or an ally within 30ft as a swift action.
 * 1/day wearer may attempt to demoralize all enemies within 30 feet as a free action.
 * If the wearer dies, the crown automatically begins casting Resurrection as a spell-like ability, which consumes the 10,000gp diamond set into the crown, on the wearer. The crown remembers the last creature to wear it continuously for 8 or more hours, and will cast resurrection on that creature should they die while wearing it even if the crown is removed from the corpse and no remains are present at the crown's moved location. If completed, the creature will be resurrected wearing the crown at the crown's location. The diamond may be replaced with any other diamond worth 10,000gp.

Mantle of Mastered Darkness 

Worn by 'Animbra' before becoming 'Animbra', 'The Immortal Scholar', 'The Shadow Lady', 'Father of Shae', OR 'Queen of Art and Shadow'. Because they presumably always wanted to be an amorphous invulnerable smoke-thing. Or, more likely, because they absolutely did not care to ever die. Records exist of several wearers indicating that either Animbra was not the original crafter, that they lost it for some stretch of time, or that they loan it occasionally.
 * +2 bonus to AC and Reflex saves. +5 on Stealth checks. These bonuses are untyped but vanish in bright light or absolute darkness.
 * Wearer gains spell resistance equal to 12 + their HD.
 * Resist cold 30.
 * While worn, wearer cannot age into middle age. If the wearer is already middle age or higher, aging is reversed at exactly opposite the natural speed until wearer is no longer middle age. If this effect ever reverses or halts more aging than the wearer could normally survive, the wearer immediately dies and is reincarnated as a shae in the shadow plane.
 * Shadow Form: 3/day The wearer may enter shadow form as a swift action. This is similar in all ways to Gaseous Form but lasts 1 hour and has a fly speed of 20 feet with perfect maneuverability. In addition, while not in bright light, the wearer gains Fast Healing 5.
