Strongest spirit in the series. Basically a genie.
Name: Uraziel
Origin: Bartimaeus Sequence
Gender: N/A
Classification: Greater Spirit, Spirit of the Ring, Genie.
Age: Unknown; presumably a few thousand years (should be older than Bartimeaus)
Powers and Abilities: Super strength, speed, durability, reactions, senses, shapeshifting (I assume so, every spirit can do it), Immortality (Type 1) magic (capable of firing off explosions, creation of barriers, compression of matter, illusion-creation, elemental-manipulation, etc. Basically any spell that any other spirit has performed and some exclusive to him), teleporation (can teleport others over hundreds of miles), transmutation (turned a Marid into a giant rock), sealing (sealed a Marid [may of been an Afrit] into a pot, and Ammet into a bottle), summoning (acts as a gateway to the Other Place).
Weaknesses: Silver and iron "cuts" through and/or repels his magic, and burns his essence. Has an aversion to certain substances. Can only act when summoned from the ring.
Destructive Capacity: CIty level (Is perhaps the strongest entity shown in the series. Only rivaled by either Nouda or Ramuthra.)
Range: A few hundred meters.
Speed: Hypersonic+ (Flew from Jerusalem to in a short time-frame to retrieve the Queen and bring her back to Solomon.)
Durability: Large-building level+ (far superior to Bartimeaus); city-level with shields (should be able to provide his shields with the same energy that he could a detonation or a similar offensive attack.)
Lifting Strength: Class M (Superior to any Marid, including Atlas who could support the weight of the Parthenon)
Striking Strength: Class MJ (Superior to Atlas)
Stamina: Superhuman to an unknown degree (Has never directly entered combat. Should be above Bartimaeus however, considering his spiritual weight-class)
Standard Equipment: The ring which he's trapped in I guess.
Intelligence: Should be of comparable intelligence to or smarter than Bartimeaus (a being who can operate on several levels of conscious thought)
