How to get Cursed Seal?

[Indigo]

okay, storm himself have asked me to do this thread so ideas he likes will be implemented into game =)
how Curse seal should be gotten so everyone were to be able get it!
give your ideas if storm takes liking into idea he will add it ingame

my own idea:

Orocohimarus experiments:

should put orochimaru back and u go to him for becoming experiment there is small chance this will happen (like 10-20% and when failed he cannot try again)

u can turn to water based like suigetsu where you cant be hurt by water jutsus and you would do double dmg with water jutsus and lightning jutsus would make double dmg on you and you would get counter like thing where all jutsus except raiton goes through you

multiple bodies like Sakon/Ukon where you would be able control your second body like puppet, and you walk over it or walk it over you you would become one body and it would get all jutsus you have

Spider like kidomaru, where you would get bigger view and would get bow, which you could shoot straigh going arrows that can pierce through and hit multiple targets and then more powerfull arrow taht you could move like kirin

All Cursed Seals would be also gotten this way
