Greetings, this is the Lord of Heroes team.
We sincerely apologize for any confusion caused by the effects of the skill 'Resolve'.
In the August update, we fixed an issue where the effects of Resolve were being applied to both squads, instead of only the squad its user was assigned to during Alliance Raids.
Following this change, we received several reports indicating that Oswald (Water) was dealing less damage.
Upon further investigation, we identified an additional issue where the damage increase effect of Resolve was unintentionally applied to Oswald (Water) multiple times.
This occurred when multiple Guardian heroes with Resolve were deployed in the same squad, causing Oswald (Water) to deal more damage than intended.
This unintended damage boost was removed in the August update, resulting in the reported decrease in damage.
We understand this led to confusion regarding Oswald (Water)'s performance, and we deeply regret any impact it may have had on the strategies and efforts of players who invested in him based on his unintended performance.
To address this, we plan to adjust Oswald (Water)'s balance in the September update to better reflect his original skill design intent.
We are taking this opportunity to review our quality assurance process to ensure a more reliable and trustworthy experience for all players.
We sincerely apologize once again to everyone affected by this issue.
