Note for Nen Pools, if your nen goes higher than level 5. It becomes level 1 because there no level 6. So this means your Nen pool will look like, level 5+level 1. If it goes beyond 5 again, it will turn into, level 5+5+1. All Hatsu must go through custom to get approved first. Nen can only be learned by learning about it by another member or control NPC from staff. Your character doesn't know about Nen either. Unless the skill says it can go beyond level five, then the skill max level is five by default.

Ten
Description: Allows the user to release and contain Nen around the body. Ten, is the process of keeping nodes open. Its about having one's aura flow through and around their body. Once maintained, it feels like standing in lukewarm, viscous fluid. It reduces the aging process of the user. It is the most basic defense against Emotional Nen attacks and offers some protection against physical attacks. Can take up to Level 1 damage before attacks affect the body. Each skill level increases how much damage the Ten aura can withstand by 1.
Restrictions: N/A.
Restrictions: -

Zetsu
Description: While Ten helps contain the flow of Nen to within a body, Zetsu is used to stop the flow of aura completely. Zetsu is achieved by closing off all aura nodes in a manner skin to shutting off a valve to make a user's presence harder or impossible to detect. However, since the user is no longer surrounded by their own aura, they are more vulnerable to attacks and the aura of others. The damage of Nen attacks that strike an individual utilizing Zetsu are increased by 1, and they are incapable of using any Nen-related abilities. However, the user gains immunity against Nen detecting abilities of the same rank.
Restrictions: Must know Ten.

Ren
Description: A direction application of Ten. Ren focuses a higher amount of aura than Ten. They project it outwards at a high rate and increase the size and the intensity. Ren increases the user physical strength and Nen pool of aura. Without Ren one cannot go far so many tend to focus it out. The user can exert their Nen in what is referred to as Bloodlust. Some creatures will use Ren for malice use and cause harm to others who cannot use Ten. The user gains Nen Pool. Level 1, the user can use up level 3 Nen without running out. Each level up, this amount increases by 1. This skill maybe train beyond level five (but remember the paragraphs to train increases too).
Restrictions: Must know Ten.

Hatsu
Description: Hatsu translates to release; act. It is the action of releasing or transmitting one's aura to carry out certain functions or perform supernatural abilities known as Nen. The user's Hatsu is influenced but not restricted by their natural Nen category. A user's Hatsu ability is unique to that individual. While it is possible to copy another Hatsu ability, it will never truly be mastered and the user's Nen potential will be squandered.
Restrictions: Must Know Ten, Zetsu and Ren.
