Of these shikigami, Hone Onna and Ittan-momen have a difficulty of Hard. Onmyoji who have been in Heian-kyo for less than 7 days can’t use them in battle for free.

New Shikigami Ootakemaru

The young master of the Suzuka Mountains. With absolute power, he stands at the peak of the Suzuka Mountains. Ootakemaru can suppress enemies by dealing multiple hits with the power of thunder, or use Unlimited Blade Prison to banish the enemy target to achieve the strategic goal and win the battle.


Trait: Earth Magic

Ootakemaru’s attacks will cause the enemy target to accumulate Ruin Lightning. When Ruin Lightning is full, the enemy target will take bonus damage.

After Ootakemaru takes part in sealing an enemy shikigami, the area around the sealed shikigami will restore his HP and grant him an increase to Armor and Magic Resist.

Ability 1: Hillcry: Thunder

Ootakemaru slashes the area before him. If the end of the AoE attack hits an enemy, he will gain a Haste effect, continuously gain Energy for Magatama Jade, and be able to use this ability again.

Upon using again: Ootakemaru summons a thunderstorm that wraps around him, dealing damage to enemies within the designated range in multiple stages according to his Energy and restoring his own HP.

Ability 2: Hillcry: Heavenly Drum

Ootakemaru casts Hillcry: Heavenly Drum at the designated position, dealing damage over time to enemies at the location inflicting Slow. Using this ability a second time will recall the Heavenly Drum early.

Ability 3: Hillcry: Swift Thunder

Ootakemaru rushes in the designated direction and enhances his next basic attack to deal AoE damage.

After an enhanced basic attack hits an enemy, some of the ability’s cooldown duration will be returned.

Ultimate Ability: Unlimited Blade Prison

Ootakemaru charges in the designated direction and unleashes the Unlimited Blade Prison, which banishes the first enemy shikigami hit within a certain period of time. While banished, enemy shikigami will be unable to take actions, lose Vision, and enter an Invincible state. Deals physical damage to the target when the Blade Prison closes.

Ootakemaru’s Attack Damage and Armor and Magic Resist will be increased according to the target’s stats for a period of time.

Ootakemaru will be available during this week’s Heian-kyo battlefield.

The Wave-washed Promise Selection Pack will also be available in the General Store. The selection pack includes the new shikigami Ootakemaru, Evolved Form Amulet x1, Taichi Mudra x1, and Eight Petals x8. You can select which to purchase!

Shikigami Adjustments


Aori’s ultimate ability prohibits enemies’ displacement, and the mechanics of her Ability 1 and Ability 3 can deal high damage to single and group targets, which have made her an overpowered performer. Therefore, we have suitably reduced Aori’s Ability Power bonus to weaken her damage output in the late game. Also, we’ve reduced the percentage of the recorded damage to multiple targets in Arachnean Circle to control Aori’s damage output to multiple targets.

Ability 1: Galaxy Amulet

Adjusted damage from 45/65/85/105/125 (+20% Ability Power) to 50/72.5/95/117.5/140 (+20% Ability Power).

Adjusted damage percentage from multiple amulet hits from 42% to 35%.

Ability 3: Arachnean Circle

Adjusted the percentage of the recorded damage to other enemies from 60% to 45%.

Ultimate Ability: Final Red Star

Adjusted Ability Power bonus of initial damage from 50% to 35%.

Rukia Kuchiki

Rukia Kuchiki is currently excellent in the top lane, yet relatively weak as a jungler. Therefore, we have suitably adjusted Rukia Kuchiki’s Ability Power bonus and increased her passive’s damage coefficient to monsters, in order to improve her performance in the jungle and the performance of her high Ability Power build.

Trait: Sode no Shirayuki

New: Enhanced basic attacks will deal 25% bonus damage to monsters.

Ability 1: Sokatsui

Adjusted Ability Power bonus from 40% to 45%.

Ultimate Ability: Tsugi no mai: Hakuren

Adjusted damage from 220/440/660 (+45% Ability Power) to 220/410/600 (+60% Ability Power).


After the previous adjustment, Satori’s batting gameplay has become smoother, but the hit rate has been significantly increased, making it hard for the opponent to dodge. Therefore, we’ve suitably decreased the Speed Reduction of Ability 2.

Ability 2: Pitch

Adjusted Speed Reduction from 40/45/50/55/60% to 35/37.5/40/42.5/45%.


After removing Vampira’s damage over time, the weakening of her strength in laning was slightly greater than we expected. We will suitably increase the base damage of her Ability 1 and Ability 2.

Ability 1: Blood Bats

Adjusted base damage from 5/10/15/20/25 to 10/15/20/25/30.

Ability 2: Blood Boost

Adjusted base damage from 80/140/200/260/320 to 90/155/220/285/350.


In addition to his relatively weak damage output in the late game, Youko’s suppression in the lane is significantly lower than other mainstream powerful shikigami. Therefore, we’ve decided to suitably increase his base stats. In the meantime, we’ve also noticed that the growth in his Ability 2’s base damage is too low. So, we’ve decided to strengthen it to provide more options to upgrade his abilities.

Adjusted base HP from 765 to 816.

Adjusted Base Attack Damage from 66 to 70.

Ability 2: Wind Blade

Adjusted base damage of the first blade from 50/75/100/125/150 to 50/90/130/170/210.

Adjusted base damage of the second blade from 10/15/20/25/30 to 10/20/30/40/50.


Kidomaru’s damage output is a bit overpowered in the late game. Therefore, we’ve slightly lowered the Attack Speed bonus of his Ability 3.

Ability 3: Raiment of the Waning Moon

Adjusted Attack Speed bonus from 60%/77.5%/95%/112.5%/130% to 60%/70%/80%/90%/100%.


Given that Nekomata’s powerful ranged harassing capability is difficult to counter, we’ve suitably reduced the cast range of her Ability 3. In the meantime, we have slightly strengthened her power in the late game as compensation.

Ability 1: Kitty Assist

Yuki Hime: Adjusted damage from (+50% (+0.75%*current level) Attack) to (+50% (+1%*current level) Attack).

Ability 3: Come in Kitties

Chacha: Adjusted distance from 1050 to 800.

Onmyodo and Item Adjustments

We’ve adjusted the strength of some onmyodo to avoid some onmyodo from being overused or others being too weak.

Summon: Purgatory

Adjusted cooldown from 8 seconds to 12 seconds, but it is affected by Cooldown Reduction.

Occult: Haste

Adjusted Haste Extent after reduction from 9% (+0.45%*Level) to 12% (+0.6%*Level).

Adjusted Slow Effect after reduction from 15% to 20%.

Occult: Discern

Adjusted Heal Down effect from 15% to 18%.

Adjusted bonus damage to shield from 20% to 24%.

Channel: Umbrella

Adjusted Shield from 160 (+40% Ability Power) (+70% extra Attack) (+16*Level) to 160 (+35% Ability Power) (+60% extra Attack) (+14*Level).

Movement Speed

Adjusted Movement Speed bonus from 8% to 6.5%.

Fire King Lance

We’ve slightly increased Fire King Lance’s damage coefficient to monsters, in hope that it will solve the issue of some shikigami having low jungling efficiency.

Adjusted damage coefficient to monsters from 275% to 300%.

New Features

Added the Switch Room Mode when teaming up. Now, players can quickly switch between game modes while teaming up, without the hassle of creating a new room.

Optimizations and Adjustments

Optimized the visual effect of the Mini Map on the right. When dragging the controls on the map to send a message, a highlight/bubble will appear in the designated area to better display the target area where the message will be sent to.

Optimized the close-up effects of Menreiki’s Lunar Fantasia skin, its transition images, the display effects in the Shikigami scene interface, and fixed its special VO effects in the Neon Rain-themed Lobby and Shikigami scene.

Demon Encounter

Kani Hime, Enmusubi, and Hako Shoujo will join Demon Encounter!

Dai Shimei’s Demon Encounter enhancement has been redesigned.

Kani Hime

Ultimate Ability: Conch Maelstrom Strengthened

Significantly increases jump range and decreases cooldown.


Ability 2: Perfect Pair Strengthened

The two targets hit by fate amulets will be linked together. If they move too far away from each other while linked, they will be pulled back together and stunned.

Hako Shoujo

Ultimate Ability: Treasure Box Strengthened

The casting range will be increased, and after collecting an enemy shikigami, she will no longer be inflicted with Slow. Enemy shikigami who are released will deal damage based on the Max HP of the shikigami who collected them and knock up enemies in their path.

Dai Shimei (Redesigned)

Ability 2: Blowing Winds Strengthened

This ability’s cooldown will be decreased each time Falsehood is detonated.

Ability 3: Young Death Strengthened

This ability’s cooldown will be decreased each time Falsehood is detonated.
