Awakening, ninja assist, assist links, myoboku stuff, nature Chakra for pos1. The best way to increase it dramatically is to do refines and purifies. Treasure tools is another good one and so is charms.

myoboku, ninja assist i think the ones that increase the base initiative stat, the others are more to do with equipment :o guess i'll focus more on them from now on

Ninja assist, assist links, mt. Myoboku, some of the outfits, summon cultivation, ninja bonds, nature chakra, are the ones I'm thinking about but may be i forgot something too.

gotcha

Group skill too. I forgot about them.

I'm lazy to read all replies, but group skills doesn't increase initiative. Unless i forgot something.

Right now best way is with Training potions. I don't think i ever invested in to other power functions, as you get all things for free just by playing.

yea gotta just do the basics and the base ini will slowly increase over time,

yep, there's no initiative here. quite sure scarlet didn't think about it and just added it thinking the feature adds other basic stats.

anyways, just to show it, those things may be quite the high amount:

EDIT: scarlet and thomas forgot to add treasure tools. those modify it too and by quite the big amount.

Treasured tool count as equipment as well.

Just click on ninjas on your team but not on your lineup. Like your sasuke out there. U will see the amount of initiative which was add without equipment instead of taking off every single equipment.

This initiative can be added using strengthen system that focus on all lineup not every position alone lime myuboku. Summon cultivation. Training potion. Home ninja. Etc

My bad.

I thought about what featured added secondary stats and it came to my mind group skills, but i forgot that initiative is the only one that isn't there.

I doubt changes much. Almost everybody has a gourd on main, just remove those 800-1000 initiative and control and you get the amount.

Anyways yes, it may be classified as equipment too even if doesn't appear on the equipment screen.

yup treasured tools won't increase base ini as it's only equipped on your team and not on every standalone ninja
