Specifically, the error originated from the Bloodline system.

The Bloodline system includes a feature that increases both Silence rate by +25% and Silence resistance rate by +25% (at level 9). This means that if two players have the same level of this feature, one player's Silence resistance will cancel out the other player's silence rate.

But it seems a bug has occurred, causing the "Silence resistance rate" to also become a "Silence rate"
Let's watch an example video I made about this bug.
In this video, I will check for bugs with the Naruto SSS character in two scenarios with Bloodline level 0 (Silence rate +0%, Silence resistance rate by +0%) and level 9 (Silence rate +25%, Silence resistance rate +25%)

45% Silence rate:                    15% Kakashi Saringan buff + 30% Skill4

35%  Silence resistance rate :  20% Susanoo buff + 15% another buff

=> 45%-35% = 10% Slince chance
As you can see in the video, it seems the silence rate has increased by over 50% at Bloodline level 9.
This bug affects all characters, please check it Admin
Thank you
