Balance Adjustments


Ability 2:

Adjusted damage from 70/110/150/190/230 (+85% extra Attack) (+8/9.5/11/12.5/14% of target’s lost HP) to 70/100/130/160/190 (+85% extra Attack) (+8% (+1.25% for every 100 extra Attack) of target’s lost HP).

Adjusted cooldown from 8/7.5/7/6.5/6 seconds to 8 seconds for all levels.

Ability 3:

Adjusted cooldown from 12 seconds to 14 seconds for all levels.


Oitsuki’s overall damage capability in the early and mid game is relatively weak, so we have increased Ability 1’s base damage and Ability 2’s damage coefficient against minions.

Ability 1: Inviting Moon

Adjusted base damage from 50/85/120/155/190 to 60/100/140/180/220.

Ability 2: Crescent Moon

Adjusted damage coefficient against minions from 1.4/1.45/1.5/1.55/1.6 to 1.4/1.5/1.6/1.7/1.8.


As the previous adjustment to Tesso did not meet our expectations, we have suitably adjusted Tesso’s burst damage and ability cooldowns in the early and mid game.

Ultimate Ability: Insurance Policy

Adjusted cooldown from 26/20/14 seconds to 35/25/15 seconds.

Adjusted Attack Speed from 2.5-4 to 2-4 (increases according to number of Coins).


We have adjusted Nekomata’s basic attack damage and the cooldowns of Chacha for Scuffling Kitties and Come in Kitties to balance her suppression capability.

Ability 1: Kitty Assist

Chacha: Adjusted base damage from 15 to 10.

Yuki Hime: Adjusted Attack Damage coefficient from 125% to 100% (+1.5%*level).

Ability 2: Scuffling Kitties

Adjusted cooldown from 9.5/9/8.5/8/7.5/7/6.5 seconds to 9.5 seconds for all levels.

Ability 3: Come in Kitties

Chacha: Adjusted cooldown from 10/9.75/9.5/9.25/9/8.75/8.5 seconds to 14/13.5/13/12.5/12/11.5/11 seconds for all levels.

Adjustments to Subdue

Currently, there is a strategy in which you carry multiple Subdues, invade the jungle while giving up minion wave resources in the early game, and then use the EXP compensation from minion waves in the mid game to quickly level up. Compared to normal strategies, you can obtain higher EXP and control capability of jungle resources using this strategy. We will try out not giving the additional EXP compensation from minion waves to shikigami who carry Subdue to balance the strength of this play style.
