Learning How To Be A Ninja

[Darkstride]

So what about Ninjutsu? What's the best situations to be using the different jutsu?

Always have Huton up. Until you get Armor Crush, you'll need to use Ninjutsu to refresh it. If your Huton buff timer has less than 20 secs, it's time to refresh.

Huton always takes priority.

For the rest:

Single target: Raiton

AoE: Katon for short fights, Doton for longer fights (if the mobs will stay in the circle and it will last it's entire duration). The best option for big mob groups is to use Katon > Kassatsu > Doton, if it's available.

Suiton: You'll be using Suiton to give yourself access to Trick Attack without needing to Hide. If Huton is active and TA is not on cooldown, then Suiton is your next priority.

You don't really need to worry too much about the rest, these are your core Ninjutsu.

As for the Mudra combos, it seems like a lot to remember but they will eventually become second nature and muscle memory will do the work for you. For ease of use, I personally have them set up on my Hotbar in the order Ten > Chi > Jin.

This way, all single target Ninjutsu moves from left to right:
Fuma - Ten
Raiton - Ten Chi
Hyoton - Ten Jin
Suiton - Ten Chi Jin

Raiton is your basic single target attack, while Katon is your basic AoE. Their cast order is opposite one another:
Raiton - Ten Chi (left to right)
Katon - Chi Ten (right to left)

Doton just needs to end in Ten, the middle mudra, otherwise the order doesn't matter.

Your buffs, Suiton and Huton are also opposite one another. Suiton goes left to right - Ten Chi Jin
Huton goes right to left - Jin Chi Ten
