Here's a quick sum up of the different bloodline and their respective gameplay. Beware, as reading this topic will spoil a large chunk of the mod. You can also just read what you want, and discover the rest through your game. But if you dont mind :

1] Pristine Bloodline [Fully Implemented]
Aka Sharingan, the core gameplay of this bloodline is centered around parricide. Killing other member of the Pristine Bloodline and taking their eyes will allow you to evolve your sharingan faster than through training, and breakthrough the unavoidable bottleneck that you will encounter later in your evolution. As your Sharingan progress, you will unlock new jutsu (Genjutsu/Susanoo...), and be able to create a Bloodline ingame, or become immortal.

2] Blood Moon Event [Fully Implemented]
As time progress, the number of member of the Pristine Bloodline will grow exponentially, as they reproduce like rabbit. But when a certain number of sharingan user come to age, there is a high chance that their combined power causes the advent of a blood moon. This moon will appears in the sky, staying here during weeks, months maybe even years, causing every member of the dynasty to fight each other in a terrible bloodbath. There will be only a handful of survivors, but they will be the best of the best. Literal monster, having probably achieve one of the highest form of Sharingan, and having capacities defying human psyche. This is not a one-time event, and will certainly happen multiple time through your playthrough. The standard duration for the Blood Moon Event is around 2 to 4 years. (This event was really CPU heavy, but it's fine now. You might still feel some slowdown, but nothing incredible)

3] Sun Bloodline [Fully Implemented]
Aka Byakugan, the core gameplay of this bloodline is centered around destiny. You have six 'rank' of byakugan that you can obtain at birth, the first three will place you in the 'Second Branch' on the Sun Family, while the three other will place you in the main one. You can not, by any mean, develop your Byakugan from one rank to another. Some rank come with their set of power that you can use, but the most powerful will require you to use 'Golden Drop'. Akin to chinese cultivation, you can 'cultivate' those drop in your body when you're from the main branch of the family. Nevertheless, if you want to unlock the ultimate Byakugan, you will need to be born with the High Tiers Byakugan, cultivate 5 golden drop, and awaken your inner power. Once it's done, you will be able to create a Bloodline, create Artifacts or even become immortal. While the Pristine Bloodline is based around killing during your life-time, your destiny in the Sun Bloodline is defined at birth, and nothing else.

4]'Grey Bloodline' [Fully Implemented]
Aka Rinnegan, the core gameplay of this bloodline is centered around age, evolution and balance. The unique way to get thise bloodline in game, is to have a child born with the Sun Blood and the Pristine Blood, and hope for him to survive through the fight those two type of blood will have in his body. If the child survive, there is a chance that he will create a new type of blood, named 'Grey Blood', allowing him to develop his body and mind through his lifetime. Evolving your eyes is the way to go, but those are so powerfull, that they will drain your health if you do not also evolve your body.
Once you get to the Third form of the Rinnegan, event will start to pop, asking you to choose one of the three 'Pearl of Domination', that will enchance your stats, namely the Mind Pearl, Battle Pearl and Vitality Pearl. Once you have the three pearl, an other event will proc, guiding you through a chain that will allow you to create an Unique Artefact. The MTTH is 25 years after you got the Pearl, and 75 for the AI. Having all three Pearl and the Artifact is mandatory to the One Man Army Event, so if the AI create the Artefact before you, you will have to steal it from whoever got it. If you want to check if the AI created it, look for the "grey_artefact_created" global flag, using the 'pgf' command in the console.

5]One Man Army Event [Fully Implemented]
Aka Rikudo
5 MTTH years after you got the Pearls and the Artefact, an event will pop asking you to Ascend as a God among Mortal. You can refuse, but the event will proc every 5 years until you accept. Once launched, you will have to fight and kill 30 member of the Sun or Pristine bloodline. They will be choose randomly, but as you will already be pretty far in the game, there will definetly be monster among the Pristine Bloodline that could kill you. Stacking a maximum a modifier is the way to go, (Duelist, Genius, Brawny, etc...), and having a 300+ personal combat stats is recommanded. Once you killed around 30 enemy in those Duel, you will be able to Ascend, becoming immortal and will become the founder of a new Bloodline. At this point, you will basically become a God, but you will still have some challenge to come in future update.


6]Battle between dojutsu user
When two character fight each other, a lot of different factor are taken into account. But most importantly, the combat rating of your character is what matter the most. Then come any trait-related combat (duelist, brave...), then any other trait that would help (genius, shrewd...). But foremost, your combat rating will heavily affect the outcome of your battle.

7]Custom Ruler
If you want to benefit any of the different bloodline without using the decision, and still getting all the event, you will need to start your character with any of those set of trait :
Grey Bloodline :
- Grey Blood
Pristine Bloodline :
- Pristine Blood
Sun Bloodline :
- Sun Blood + (Main Family and either Superior/Great/High Byakugan) or (Second Family and either Low/Inferior/Middle Byakugan)
