When Kela'ra saw the form of Astaroth change for the third time, his mind was in disarray.
'Is this kid just an illusion? Was he conjured by an elf mage to tire me out?'
It had been so long since he was hiding, it wouldn't be the first time they used such a ploy against him. He wasn't sure if he should keep fighting or find the source of the illusion.
But when Astaroth's next attack connected, he immediately dismissed the illusion theory. Astaroth started shooting firebolts, icicles, stone bullets, and wind blades in quick succession.
The attacks connected with Kela'ra's weapon, and he knew by the pressure that these spells weren't fake. And it was well known that illusions couldn't fire proper spells.
This marked Astaroth as a very real opponent, and it terrified him. His mind immediately went to rogue experiments.
