Allow me to begin with the Kekkei Genkai. Although I love the concept and how it is laid out, it is incredibly OP. Way too op in fact. This fog not only allows you to decrease vision, but large percentages of other senses as well, along with giving you chakra sensory. Chakra Sensory is strictly for the Clanless other than Hyuuga and Uchiha which are canon clans. Here are other aspects that are too much.
- The Fog has no limit in use or range. In this site, the Hidden Mist only covers certain range.
- You cannot summon actual lightning from the sky. It's auto kill and banned from the site.
- The other levels are too Manipulation based with no chakra cost such as paralyzing just by touching and making electrical prisons.
If you want this mist, here are some adjustments that will maybe allow you to keep it. You can summon it as Kekkei Genkai but it needs limits. It has to have a range and it has to have a limited duration. If you cast this, it can boost your clan hiatus by 20% in damage (One Rank Increase). Either choose the stat reduction of your foe but the numbers have to be reasonable.
Seeing such effort, I hate having to crush it, but this is my job. Great Concept but is just too much.
