As the Echo Revenant died, Sebastian felt an overwhelming rush of energy flood into his body.
"HAHAHAHAHHAAHHAHAAHA."
It felt amazing, like always. Power rushed through his body. His mana grew, and so did Sebastian's physical strength.
The amount of excitement he was feeling could not be quantified. But the rune master knew this was still not enough.
To reach the second compression level, he needed more than just this boost.
A grin spread across his face, wide and unrestrained, because albeit it wasn't enough to have enough mana to power up his own mana cluster, what he got was still an enormous amount of mana from a single creature. It was an amount unheard of, even for him.
