Dojutsu

Dojutsu is a Mod that will give you the eyes from Naruto, the mod is still in beta, but you can try the mod already and write your ideas and feedback, the Mystery eye can you get from a wandering trader and in archeologie, when you get hit you have a 1% chance that the eye will crack in your inventory, then you can roll for one of the three eyes, with a chance of 20% of getting the Rinnegan, if you dye that cracked eye in white oder red then you can change that action in 80% getting a sharingan or byakugan but with 0% of getting the rinnegan, you can only roll ones for eyes on each server and if you try to roll again you will get other items like headband, cosmetik upgrade or other small helpful items

for short, tomoe 1 sharingan will let you see the way how projectiles fly, 2 tomoe will let you fokus on mobs to predict there future and always sees the future of badmobs, tomoe 3 will give your enemy a new effekt that let him attack slower and also has the chance to give them the genjutsu effect, you can check the rest for yourself, also, to upgrade tomoe 1-2 you have to use it active in your inventory,

I will make this describtion later better
