The "Thousand hands Bodhisattva" is said to be the ultimate technique of Buddhism where the user would be able to use all of the thousand hands to contend against an opponent who is even two realms above.
But, it has its own difficulties. One is that it's extremely tough to master it. The knowledge can be acquired from the Reaper but mastering can only be acquired by practice. Without mastery, Azzy cannot use it to its full potential.
And the other difficulty is that the technique is time-limited. Even the one who mastered it cannot maintain this state for a very long time.
Azzy knew that very well but he couldn't help it when he can't reveal his Arcana or even soul energy and on the other hand, the opponent is someone like Ragron. So, he needed to go all out.
After activating the technique, Azzy didn't waste any time and attacked Ragron by pushing forth his palm.
