So the current and only event that in the public version I have listed that can allow the Three Tomoe Sharingan is "LVL.06" It would seem I messed up on it lmao.
I used the on action command "on_blood_brother_death" while half awake without thinking as that's for khan clans I believe.

My bad i'm sorry, I really should of fully tested it.
I'll try to fix it soon enough as well as adding in a few other things, though i'm not sure how to exactly change it as no on_action would really fit so i'd need to make a few events with event_target:'s to select someone close to you then kill them off if the option is selected ending with a result to possibly get the eyes from a chance roll.

Would you be able to tell us the trait name for the Completed Sharingan please?

Oh so there's not really a way to evolve it from the Second Tomoe just yet?

Can there also be another way to a complete sharingan? What about parent dying? Cause I created a hybrid/Valyrian/Uchiha clan and I had like 15 children.

Interesting some developed one tomoe, some developed two tomoe. What I found interesting is that there may be certain characteristics that can maybe speed it up a bit. Like Ambitions, Brave, or having high martial ability.

This mod is really gonna be good once it is fully completed. I think three tomoe should also be developed by battling experience as well. Maybe being in a certain amount of duels or battles during war.
