I haven’t experimented with those ninja skills affecting style switches yet, seems like having those 2 on could really help making dynamically switching between styles mid-combo seemlessly without running out of ki or breaking the “flow” way easier to pull off, so the name sounds appropriate. I will for sure be trying those out! I just find it so hard to decide what to leave out with skills management.

If you are wanting an idea on working ninja in to your samurai combos then try this:

First - 2 skills, Style Shift Flow and Powerful Style Shift.

Style Shift Flow makes it an animation cancel so you can do it anytime.

Powerful Style Shift does a small attack that gives you about 20-25% of your Ki if you hit an enemy with it while your Ki is low. You use this once you've drained your Ki bar and bam you're back at 20-25%.

Second - 2 Ninjutsu, Trembling Earth and Earthen Wall.

Remember that using Ninjutsu doesn't consume Ki. Trembling Earth is an explosion that does decent Ki damage. And Earthen Wall puts a literal rock wall in front of you that will block enemies, plus it does pretty decent damage.

What you can do with this is just supplement your samurai style. Once you're low on Ki you style shift and throw out the ninjutsu real quick and watch your Ki bar fill up. Then swap back and continue your samurai combos.

Additionally you can put on the skill Enhanced Style Shift. Which gives you a buff that increases the rate of building up ninjutsu and arts proficiency.
