The bead he was talking about was one of their life-saving treasures within the Demonic Cult… This bead can enhance their abilities to be protected by a pure and unsullied Aether that would last for a while.

Apparently, after their initial confrontation with the Celestials, Altair realized that he had actually underestimated the Celestial Beings this time.
He didn't expect that he would encounter a high-ranking Celestial!
If he would make a guess, he believes that they are certainly ranked under 100!
If they were only Unnumbered Celestials or perhaps, those at the lower end of the ranking, he was confident that their suppression was more than enough to stop them for about five minutes. At that time, the other members of the squad should've killed their contractors already…
