Worldbreaker!

In the Mysterious Bone Forest, an ancient forest island that separated the Blood-Smelting Kingdom and Seafaring Nations from the Sanctuary, Hakim ran for his life, desperately teleporting from one shadow to the next. 

The might of a Blood Noble typically changed according to the intensity of ambient sunlight. The brighter the light, the weaker the Blood Noble. This was one of the few rules that even the Fylkirs couldn't escape. 

As a matter of fact, the closer to the first generation, the more extreme the variations, with Fylkirs not able to use over 33% of their powers at noon, but up to 300% at the Zenith of the Night—or midnight in general. Hadubrangr's restrictions were the worst…or best, forcing him to go from 20 all the way to 500% in a 12-hour span.
