Dear Traveler,
Our technical team has thoroughly reviewed the relevant battle data multiple times and found the following:
When Maashtur used the battle skill, the primary attack target was Garius, and the battle skill was then released on Ardreth. At that moment, both Maashtur and Ivellios were set to attack Ardreth. However, due to the distance between Maashtur and Ardreth being 2, while melee units have an attack range of 1, Maashtur found that the distance to the target was greater than the skill range on the next attack. As a result, the current attack target was cleared and a new target was selected, which was Paixton.
Therefore, the battle skill did indeed take effect. Even though the primary attack target was set to Ardreth, due to the distance mechanism for melee attacks, the target was cleared and reassigned.
Thank you for your patience and understanding.
