I'd like to get a few more eyes and opinions on this item of power. It's for a character of mine (Champion of God, if that matters). I think it's pretty balanced but I wanted to get a few more opinions. Is it too powerful? Not powerful enough? Just right?
[-3] Solomon's Guard
Description
When the old wise king Solomon passed from the land of the living, the guardian angel that protected him set aside its sword, its duty complete. The sword did not join its master in retirement but instead appeared to those who shared its purpose, to protect and serve.
Solomon's Guard, also known as the Shining Blade, is a short sword of angelic make. Its blade is slightly longer than a man's forearm and made of a silvery material flecked with gold that is as strong, if not stronger, than steel. Three words are inscribed in Latin on both sides of the blade: 'Duty, Honor, Sacrifice'.
Musts: You must have a calling or destiny to inherit Solomon's Guard, one that coincides with its purpose, usually is represented by a High Concept.
Skills Affected: Alertness, Conviction, Empathy, Lore, Weapons
Effects:
Angelic Origin. This blade was wielder by an angel and shared in the angel's nature, making this weapon a powerful holy symbol in its own right. Its very touch is like holy water or that of a cross or other symbol of faith backed by the belief of the possessor.
Divine Light. Solomon's Guard is lit from within by a soft white light. It provides a diffused glow that is sufficient in strength to illuminate one zone of mundane darkness.
Divine Purpose. Solomon's Guard may only be swung with true selfless purpose in mind and heart; if this is not the case, the bond between the Knight and the Sword is broken and may only be restored by undergoing some sort of trial of faith. When swung without such purpose in mind and heart, the blow does not land (any attack roll automatically fails), the bond is immediately broken, and the sword falls from the wielder's hand.
Basically, the GM and player should look at the description above as a guideline for how to compel the high concept attached to the sword - your character might be tempted to use the sword for selfish reasons, and could either receive a fate point to stay his hand or succumb to the temptation and lose the sword temporarily. If another takes up the sword and swings it selfishly, your Knight is still responsible for how the sword is used, with similar repercussions.
Duty. While wielding this weapon, you cannot be turned from your duty. When swung in keeping with its purpose, Solomon's Guard grants a +1 to the wielder's Weapons skill.
Honor. The honor of this blade illuminates the wielder's path. In the presence of acts this blade finds to be dishonorable, it glows fiercely, alerting the wielder to danger. It provides you with a +1 bonus to Empathy when detecting lies, +1 to Alertness while Avoiding Surprise, and +1 to the Mystic Perception trapping of the Lore skill.
Sacrifice. While wielding Solomon's Guard in defense of others, the blade hardens your Convictions into a brilliant aegis. You gain Armor:2 against all physical stress). When facing an opponent offensive to your faith, you may spend a fate point to increase it to Armor:4 for the duration of the scene.
It's a Sword. Solomon's Guard always takes the form of a sword, though the precise type of sword may change through the ages. As a sword, it possesses the damage and other attributes of any sword (page 202).
Unbreakable. As an Item of Power, it cannot be broken, save through dedicated magical ritual predicated upon perverting its purpose.
Discount Already Applied. As an Item of Power, Solomon's Guard already includes the one-time discount (page 167). This means that if the character possesses more than one Item of Power, the one-time discount will not apply on that second item. If Solomon's Guard is the second or subsequent artifact the character gains, the refresh cost is –5.
