Hello,since i am a fan of death note and i always wanted to use a death note mod but unfortunatly i don't know how to code so
Here are my suggestions:
First,you should have the ability to write a name in the death note and the name written should die in 40 secs. And please make it for 1.7.10
then, ( tbh this part isn't thaat needed cuz i just wanna kill peapol xD) You can add a shinigami dimensions and some shinigami's like ryuk and once you get a death note he should follow you every where you go and if you make death note randomly fall it would be kind of unfair for players cuz it's luck based so i would say that you should make a portal and go to shinigami dimension and go to the shinigami king and make a hard quest.
also,add shinigami eyes these eyes should either give you the ability of /invsee or /player info or you can make all names in this mod invisible and shinigami eyes let you see them and to get the shinigami eyes you should also interact with the shinigami but the cost for it should be cutting the health of the player permanatly ( for example in a normal world if you got 10 health bars it get reduced to 5 permanatly and can't regen with golden apple or something ) and if you die you loose both of death note and shinigami eyes.
Ok,that's all what i can see atm i hope this mod get relized
