The Phoenix Armor is a set of flowing, white robes. The length of the garment is unknown. All that is known is that when it is in the hands of all but a True Vampire, whoever attempts to don it suffers immensely. The garment houses the soul of a phoenix, and it burns all who are not similar to the one who defeated it. No other protective garments, trinkets, or armors can be used when it is donned. No other armor is comparable to it. The cloth augments the user’s strength, speed, and endurance, allows the construction of near-indestructible constructs, and is near-immutable to even the strongest of sorceries.
