I'll help You nikk and most peopel like myself has problems with Jujsu making. So There should be 5 elements and different type of Jujsus. here is the list of some that are basics
Tai: Physical attacks
Nin: Enchantment attacks like elements
Gen: Illusion
Tai is a basic attacks that requiers know Handsigns I've heard but Nikk should know
Nin is enchantment that can increase and stats Like speed or Intel, also they as well can be use as element attacks or defence Like Chidori is a lightning element,
Gen Is illousion attacks that Like Nin but inseted they confuse the opponets and My leave them in a come or something like that but you can be relesed from this by a medical ninja with you must have one on you're team.
The list of the elements are. Fire,Water,Earth,Wind,andLightning I think.
Now the basic of this is that you can choose with style you can choose as well as by stats, Don't use something that dosen't make sense. and for jujsu ideas make sure that Nikk can see and rank them by there Descriptions that was Nikk can figure out if it is a E,D,C,B,A,or S. Later.
