Shield Maiden

 This class is complex with many abilities that can turn battles in an instant. There are a lot of mentions and ties to Norse Lore and Mythology, it would be advised to put forth some effort to research so you know what your dealing with. Shield Maidens themselves have a very strong sense of duty, honor, and authority in the field of battle, at home, or elsewhere and typically inspire reverence and courage in others just by their presence. Shield Maidens tend to fall mostly along the Good and Lawful axis of alignments but can be anything including evil. So enjoy building and becoming not only a very powerful warrior but one that invokes great awe in her allies and dread in her enemies.

Once per Week you may call out to the gods and ask for their direct aid in something. This functions like the spell wish except the following changes.

The Gods will always act in your favor, if you fail to word something precisely enough the Gods will try to interpret it in the most favorable manner. You are after all their servant, an astoundingly accomplished one at that. (Though if Loki answers expect things not to go quite right or result in some humorous circumstance regardless of how well it's worded)
You do not suffer from the Stress of casting Wish and you'll never lose the use of this spell.
You must make a DC 15 Religion Check when using this spell. Success indicates the spell goes off without a hitch. Failure means the spell fails to activate and nothing happens.
