Generally speaking, when a Pet Beast uses a skill, it will indicate beforehand through its movements, eye color, or calls. But just now, Lubao did not show any sign of using the Ice Flower Seal; the cold qi emitting from its body merely froze the ground into ice.
Auroal pondered and said:
"When the skill proficiency of the Ice Flower Seal reaches the Mystique Level, the Pet Beast indeed doesn't need any actions to cast the Ice Flower Seal, but the surrounding temperature still drops significantly, allowing us to judge whether Ice Saint Ya is using the Ice Flower Seal based on temperature."
"However, as soon as Ice Saint Ya appeared, the temperature of the entire field dropped, so unless a Pet Beast is particularly sensitive to temperature, it's still hard to tell." Nephthys said.
