Fenrich

While within Skysea, Fenrich is powered up significantly by the eight moons there.

-The moon he's under provides the most benefit, and the two adjacent moons provide a lesser boost. The remaining five moons still provide a very minor boost to his power.
-He's affected by the resistances of whatever moon he's under. In the purple lands he develops a resistance to ice and cold that allows him to function to an extent despite the frigid wasteland. However, he becomes more vulnerable to fire.
-While in this world, his energy levels are significantly increased, which can result in him having trouble resting until he's gotten used to it.
-He can learn the spells without the use of moonstones, but at a slower rate. He also can't learn skills from an area he isn't in even while practicing with skills of that element. If he wants to learn more fire skills, he needs to go to the Red Lands, for instance.
-He's strongest in the Green Lands, his own natural element, but is stronger than usual wherever he is.
