He gave the staff some tries to see how well he could enable the design to draw mana and disable progress.
With the help of the Spirit Hammer's adjustments, he also changes the design to let out the boosted mana in a spherical shape at the top of the staff.
He gathered enough mana and cast his DOME OF SILENCE.
Shadows started being created by the tip of the staff and surrounding Shingi and started forming the Spell's usual spherical form.
The Spell finished forming in 10 seconds, which was better than the usual time that it was taking Shingi.
This was because he had to manipulate Dark Mana of the shadows surrounding him, which gave some resistance, so it was increasing the time to finish the Spell. But now, using the mana of the Mana Gem didn't have this kind of resistance and was almost like he used his mana if he could produce that Element with his Mana Pool.
