Rui nodded, absorbed. He knew that domain techniques covered a lot of areas intrinsically; it was what defined it and set it apart. This naturally meant that a lot of energy was spread out, resulting in low energy density, which could easily result in a weak technique whose effects are too spread out.

"The most common means by which this shortcoming is solved is by ensuring that, despite being spread across a large area, the entire area impacts the target of your technique in some way. If the entire area that is receiving energy from your domain technique is impacting the target directly or indirectly, then the total spread energy will end up impacting your target directly or indirectly," The Master explained. "In this case, the low energy density doesn't matter because no amount of energy is being wasted. The entire area impacting the target means the entire energy you are outputting is hitting the target. Suppose only a portion of the environment is impacting the target. In that case, the energy in the rest of the environment will not impact your target, and thus will be underutilized and wasted."

That made sense to Rui. This way, the domain's shortcoming was mitigated while its advantage of highly successful hit rates was retained.

"That is the most common consideration regarding the field of domains," Master Gurren remarked. "However, it is not the only one. Domains may seem simple conceptually, but in my many years of exploring, I have come across immense depth in them that they are never given credit for. That is what I will convey to you, arrogant brat."

Rui nodded, smirking. This was why he had come to Master Gurren instead of just searching for random domain techniques in the Martial Union's library.

holds back the field of domains from becoming mainstream is the difficulty of individualizing them," Master Gurren explained.
