Adam didn't fully understand this because he took it for granted, but there were very few Phantoms like him who had absorbed both the Midnight Crystal and the Twilight Crystal. It was very rare that one altered part of the power gave such Phantoms an advantage.
In Adam's case, it was the Foundation Artifact, which was still under the influence of dense, black energy and was inaccessible to Adam. Moreover, one of Silvana's abilities, which had not even had time to appear, was in the same state.
His power would be able to help him later, but the energy could already affect the monsters now. Sure, Adam couldn't control the other monsters or cause them more harm, but the fact that he had the energy of the First Star was significant to many.
Especially to those who considered the First Star to be the most important thing in this world, and it was practically sacred.
Crack.
