After some years, Gravis lost himself again.
And after seemingly no time…
BOOOOM!
The Law of Inferno's Efficiency was comprehended!
Gravis could now combine the Law of Inferno's Efficiency with the Laws of Inferno's Heat and Inferno's Decomposition to give his attack more longevity. The Law of Inferno's Efficiency would cancel out the heightened Energy cost of the Law of Inferno's Decomposition. However, that was only for his own Energy. The enemy would still feel the full effect of the Law of Inferno's Decomposition.
This combination was extremely powerful.
These Laws allowed Gravis to attack a vast area with the power of a level five Law. It was still weaker than his Lightning Crescent, but the advantage was that the enemy couldn't evade this attack.
This was just as powerful as Samantha's Domain of Cold back then.
'444 years. I'm becoming faster.'
Gravis answered his questions again and went to the next area.
