Spell Master

A Spellmaster is a human who made a contract with a demon, but unlike a common contract, it is not on equal terms, instead giving full control to the human. With this type of contract a human is able to master and use the demon's power as his own, in the form of techniques called "Spells". It also seems that spellmasters do not require their demon to be in the immediate vicinity to make use of its power, where as normal contractors do.

Abilities
Being a spell master offers the human contractor a multitude of different abilities. They can vary from person to person, but some of the basic abilities they all seem to share include:
 * Enhanced Strength
 * Enhanced Speed
 * Enhanced Endurance
 * Enhanced Reflexes
 * Contract Seal
 * Seal Manipulation
