Kagerou and Oboro clans were once known as the Right and Left hand of the Feudal Lord in Amatsu. They displayed fearsome prowess, completing every task swiftly with precision. Perhaps due to Kagerou and Oboro's outstanding abilities, they were banished from Amatsu by the Feudal Lord who has grown fearful of them. Betrayed by the Feudal Lord, it is said that Kagerou and Oboro have hidden themselves in the shadows of history.

Decades have passed since then.

A new group of clan calling themselves the "Ninja Clan" have appeared in Amatsu, who has steadily gained power over the years. It is rumored that the Jounins of the clan will teach experienced Ninjas, who pass the secret test, the ways of Kagerou and Oboro.

Stat Amount Notes
STR 1 ~ 80
AGI 1 ~ 90
VIT 80 ~ 100 Overall survivavility.
INT 100 ~ 120 Base damage.
DEX 1 ~ 110 For cast time.
LUK 30 ~ 60 Small bonuses, extra MATK.

This build is similar to Oboro's predecessor class, Ninja, and utilizes same offensive magic skills and new supportive type magic skills. INT, DEX and LUK are the primary stat for Magic build to increase MATK output as well as decrease cast time of skills. One can opt to completely drop the DEX stat in favor of other stats such as STR and AGI with the use of Cast Time reduction equipments and 16th Night skill to increase weight capacity as well as increase ASPD. Note: 16th Night skill stacks multiplicatively with all Cast Time reduction skills, equipments, items and stats.

Oboro's primary damage and supportive skills are Freezing Spear, First Wind, Flaming Petals, Exploding Dragon, Ninja Aura, Cicada Skin Shed and healthy mix of Ninja 2nd tier magic skills such as Blaze Shield. There are new supportive skills that both Kagerou and Oboro classes can get such as 16th Night, Pure Soul, Fire-Charm, Ice-Charm and Wind-Charm that directly or indirectly increase throughput. An Oboro exclusive skill, Distorted Crescent can also be used to increase MATK substantially.


Stat Amount Notes
STR 90 ~ 110 Base damage.
AGI 80 ~ 100 Present in calculation of Swirling petal.
VIT 80 ~ 100 Overall survivavility.
INT 1 ~ 80 SP pool and SP regeneration rate.
DEX 80 ~ 100 Present in calculation of skills.
LUK 1 ~ 80 Small bonuses, extra ATK.

Throwing builds utilize newly strengthened throwing skills available to Kagerou and Oboro. The main throwing skills that are available are Swirling Petal, Kunai Splash, Kunai Explosion, and Rapid Throw.

With the exception of Rapid Throw, all throwing skills are based on STR to increase ATK, and DEX to increase the skill modifier. In the case of Swirling Petal skill, it utilizes the AGI stat in its skill modifier formula. Having high amounts of DEX and LUK will allow Oboro to increase HIT and ATK of throwing skills as well as reduce cast time. It's worth noting that 16th Night skill will reduce significant portion of cast time of all skills so it's recommended that players don't focus too much on the INT stat.

With the combination of old and new supportive skills such as Ninja Aura, Cicada Skin Shed, 16th Night, Pure Soul, Charm-Earth, Charm-Fire, Charm-Ice, Charm-Wind, Cast Ninja Spell, and an Oboro-exclusive skill Distorted Crescent, Oboro can deal substantial damage to their foes.

Killing Stroke

Stat Amount Notes
STR 100 ~ 120 Base damage.
VIT 100 ~ 120 Better HP pool for both damage and survivavility.
DEX 40 ~ 100
LUK 40 ~ 100 Perfect Dodge, extra ATK.

This build focuses on the Ninja's skill Killing Stroke, a mini-Guillotine Fist of sorts. STR and VIT are the two stats driving Killing Stroke's damage and are thus the main stats for this build. DEX and LUK can be used for Rapid Throw skill in conjunction with Killing Stroke to significantly increase the chance of killing your target. DEX also helps marginally with ninja skills cast time, but majority of the cast time will be reduced by 16th Night skill. A pure Killing Stroke Ninja may opt to discard some DEX and LUK in favor of additional STR/VIT for Killing Stroke damage but this is not recommended as the damage gained does not justify losing the benefit of Rapid Throw skill.


Oboro cannot wear transcendent-only or 3rd class-only equipments. They are limited to equipments that's wearable by all, ninja, kagerou/oboro, and 2nd class equipments. This means that equipments such as Nidhoggur's Shadow Garb, Variant Shoes, Valkyrian Armor cannot be worn by them.
