Adrian wanted to know if his other abilities are grayed out or unusable. Luckily, he can still use his domain skills which means he has a chance to easily finish this job. The only reason he has not attacked is the aura that the four vajras that Chidaide is holding.
The four vajras is releasing an aura that is peculiar and distinct. Adrian has to test out the waters in order to see what those four vajras can do. He also did not know how long he will be trapped inside this mirror dimension.
He wanted to know if this pocket dimension is everlasting or just until one of them drops dead. Adrian is not even sure if their bodies are sent in this pocket dimension. The thought of having a Psyche Armament that transports their bodies is not ordinary so he is sure that only their souls is pulled to this dimension.
