The cavern resonated with the demonic muttering as the wounded Belthazor stood before the energy source.
With an ominous energy flow, the demon began absorbing the essence, attempting to regain some of its peak form.
"You arrogant human... I will bury you here alive," the demon mumbled, its voice dripping with malice as it harnessed the power flowing from the spatial slit.
'Tch.'
I clicked my tongue, realizing that the battle was about to take a more challenging turn.
The demon, fueled by the absorbed energy, would undoubtedly become a more formidable opponent.
As the demon completed its absorption, a surge of power emanated from its form. The cavern seemed to tremble as Belthazor stood, rejuvenated and more menacing than before.
–SWOOSH!
I readied [Celestalith] in its bow form, determined to continue the assault. However, as I released an arrow towards the demon, I witnessed a distortion in the space around it.
