You have been given the Odin Force, the power of the Kings of Asgard since the time of Odin. It is only a shadow of itself at the moment, but will grow to the full force in time.
This power is near-infinite and seems to allow Odin, and later Thor, to become almost invincible, and seems to allow its wielders to rival the powers of the strongest beings in the universe. The limits of its power are unknown, but it adapts to its holder, enhancing all aspects of their power, from physical, to magical, to divine, allowing for just about anything, only limited by your power & imagination.
Beware of overuse, for if overused you will be forced to enter a deep sleep to recover from overreach - leaving you vulnerable in the process.
