Special abilities tend to be unique to one shinobi, whether an odd bloodline or the result of an experiment. Kekkei Genkai are bloodline traits that a shinobi possesses from birth.
If an ability or kekkei genkai you want is not listed, or you would like to request an additional slot for an existing ability, PM an admin and ask for it to be made available. Your request may or may not be granted.
Sennin, or sages, are shinobi that have mastered the use of senjutsu and Sage Mode. They are very rare and very strong, rivaling Kage in power. Each sage is tied to a specific animal summoning contract.
No one member is allowed to have two sages at one time, no exceptions. If you would like to change the contract animal, PM an admin with your request, which will be granted so long as it is reasonable.
A sage may take an apprentice IC. There is a one in two chance of the apprentice surviving their first attempt to enter Sage Mode. An admin will flip a coin to see whether they survive or turn to stone.
