NIN Optimal Rotation Help

[AdamFyi]

The rotation actually adds up because of how flexible it is and how it isn't as restrictive. I'm currently at 45, so I can't say that this may be the optimal, but it's the one I use personally. So first we're going to add in the skills that have a combo chain. Note that this is assuming that all recast timers are set to 2.5 seconds, and that it's against a single enemy.

Spinning Edge > Gust Slash > Dancing Edge > Mutilate > Spinning Edge > Shadow Fang > Spinning Edge > Gust Slash > Aeolian Edge > ...

You want to reapply Dancing Edge, Mutilate, and Shadow Fang whenever their timers get to about 8-ish seconds. Dancing Edge has a higher priority than the DoTs because the damage is further increased by the debuff. If all 3 are up, you do the Aeolian Edge skill combo till one of the buffs wear off. Weave in Mug, Juguate and buffs whenever they are available. Also you can alternate between Kiss of the Wasp and Kiss of the Viper whenever needed.

Now we weave in the mudras!

Huton (Jin-Chi-Ten) > Spinning Edge > Gust Slash > Dancing Edge > Mutilate > Spinning Edge > Shadow Fang > Spinning Edge > Suiton (Ten-Chi-Jin) > Sneak Attack/Trick Attack > Gust Slash > Aeolian Edge > ...

At this point, if both Huton is up and Sneak Attack/Trick Attack are on cooldown, you want to only use Raiton (Ten-Chi). Otherwise you are free to reapply Huton and Suiton whenever they come up. Otherwise, Raiton all the way! As for Doton (Ten-Jin-Chi), you can weave that in for the extra DoT buff it leaves on the floor like Shadowflare. However, Kassatu should only be used when you can throw up a second Raiton because of its high potency. But feel free to use Kassatu should you flub a mudra.

And that's all I have so far. I'll look into it more once I get to 50.
