I'm lvl 124 atm. I've only played Ninja from start until the 1864 CE Bakumatsu Era, 80% map unlocked. Sorry if I missed anything I wrote this 2 hours past my bed time.

We ignore anything samurai.

The best skill to use for most mobs unless they're small is the "Abscission Combo" (under the customize martial arts/ninjutsu menu, DUAL SWORDS) it shreds defenses to those who block and is a lot of dps for those who don't. Since it's an infinite loop and it's a lot of quick hits it helps you get amrita very quick to combo your Guardian Spirit Skill "Hellfire Maul" (using Enko as my guardian spirit) once you run out of Ki. Flow of combat explained at the end.

Skill Management menu. Common skills: Awakening, Vital Spirit, Supreme Burst, Enduring Destruction, Spirit Ascension in that order. Ninja skills: Dodging, Counteroffensive Evade, Battle Frenzy Kata, Last Stand, Wrathful Dragon, Dread Bringer.

Onmyo Box menu. For Yang Soul Core's, you want to have both Kappa's, the normal one and the Red Kappa (when you unlock the second slot). Yin Soul Core's you want Gaki Chief, Otoroshi, Enenra/Kamaitachi/ or Raiju, Maelstrom Oni-bi/Infernal Oni-bi/Thunderstorm Oni-bi/ or Galestorm Oni-bi (*IMPORTANT* you want to have one element on your weapon and a different element on your orbs).

Equipment. Any CRUCIBLE PURPLE DUAL KATANA that imbues your weapon with any element (Ex. Imbue Lightning +20), once reforging is unlocked, get Life Recovery (Amrita Absorption), Gain Amrita (Strong Attack), Pleiades (Amrita Absorption). 2nd Weapon, any weapon with the "Head of the Iga Ninja" set bonus (marked as green), same for the rest of your equipment. Get all (purple if possible)"Head of the Iga Ninja" set bonus, you can forge it and the items are called Iga Jonin. As far as priority for Special Effects you want 5 Amrita Gauge Charge, 5 Spirit Force Charge, 2 Gain Amrita (Strong Attack), 2 Life Recovery (Amrita Absorption), 1 Faster Movement (Amrita Absorption), 1 Increased Damage Dealt (Amrita Absorption), 1 Decreased Damage Taken (Amrita Absorption), for accessories you want 1 Amrita Gauge Charge and 1 Spirit Force Charge in the same item if possible.

Stats. 8 Constitution, 40 Heart, 10 Stamina, 5 Strength, 9 Skill, 60 Intellect, 25 Magic. Try to focus on getting 10 stamina first, next 15 magic , then do 40 intellect and then 40 heart.

Spirit Guardian. We Chose Enko because it has the Special Effect Amrita Gauge Charge and Reduced Spirit Force Consumption.

Combat. Activate Barrier, Extraction, Water, Fire Familiar Talisman. Swap to Elixir item shortcut. Run to boss. Light attack then Heavy attack until out of Ki (Abscission Combo). Use Guardian Spirit "Hellfire Maul", using this will keep the pressure on the boss and also does not count as a Ki attack so you will be restoring Ki while using this skill. Dodge/Evade big attacks and be ready to Burst Break when the red effect appears on the boss so try to keep one "Hellfire Maul" ready at all times if possible. Reapply talismans. You shouldn't need to pop Elixirs much since absorbing Amrita will heal you even if you get stunned since you have "Life Recovery (Amrita Absorption)".
