Unorthodox Schools

There are as many unorthodox techniques as there are orthodox ones. This is just a sample.
The School of the Caged Sun: (Metal/Lightning/Solar)

This unorthodox school describes how to build a caged sun. A mechanism of merged metal and qi that is powered by a practitioner's own soul. It takes significant effort to build and stalwart willpower to fuse it with your own soul, but once activated it generates a "Caged Sun" a source of constant solar Qi that draws in surrounding qi of all types and converts it into a torrent of pure Qi for the cultivator to use. The Caged Sun is both a source of Qi and a massive reservoir allowing a cultivator to hold far more than their realm would suggest.
