Basically Ninja AoE Rotation

Basics:
- You want to use your AoE rotation only on groups of 3 or more mobs. You actually lose damage if you aoe 2 mobs, so its better that you use your single target weaponskill rotation with some Hellfrog and Katon here and there.

Lvl 1-34: You don't have any AoE rotation and your as slow as a turtle.

Lvl 35-44: Spam Death Blossom, and use Katon as soon as your mudras are off cooldown. That's it.

Lvl 45-51: You can now cast and maintain your Huton speed buff, and cast Doton. So now, your aoe rotation goes as follows: Death Blossom -> Doton -> Katon -> Death Blossom spamming -> Doton. Also, don't forget to cast Huton once in a while to refresh your speed buff

Lvl 52-61: At level 52, you get the brand spanking new weaponskill Hakke Mujinsatsu that you use after every Death Blossom. Now you don't need to worry about running out of Huton, since you get back 10 seconds every time it is used. From here on out, your aoe rotation is not going to change much at all. Death Blossom -> Doton -> Hakke -> Katon -> Death Hakke combo spam and repeat.

Lvl 62-80: Nothing changes, except that you learn Hellfrog Medium and gain the ninki resource and its bar. Every time you hit 50 ninki, use the frogger right away.

Side Notes:
- Please, for the love of the Twelve, DON'T USE TRICK ATTACK WHEN YOU HAVE A GROUP OF 3 OR MORE MOBS Cause its not worth it, and using it on bosses or on a single healthy mob is much more advantageous.
- Ninja also has other skills like Kassatsu, Mug, and Meisui that could help increase the frequency of jutsu casting and frog summoning, but I don't recommend using them for trash mobs, and I reccomend you save them for bosses instead. Mug gives you 40 ninki, but its a single target damaging move with a long cooldown. Meisui wastes a jutsu cast to get 50 ninki, and is also on a long cool down. You could use Kassatsu for Gokka if you need that extra damage, but its cooldown is the same as Trick Attack's, and using Hyosho Ranryu in the Trick Attack window is ridiculously strong, so, again, I prefer to save kassatsu for bosses.
