Since the Ferae Adamantine Insolum Beetle was a world boss monster, there was no true limit to the distance it could chase after Izroth. If it was a truly vindictive beast, it could very well follow him all the way out of the Ferae Jungle and even the kingdom of Tempest itself!
But the chances of that happening were not high. The reason for that being Izroth figured as long as he showed the Ferae Adamantine Insolum Beetle the possibility of catching him was not worth the effort, it would willingly back off after a while.
Izroth moved through the multitude of natural obstacles that existed in the Ferae Jungle at his top base speed. However, no matter how skillful his movement, Izroth was unable to outright shake the Insolum Beetle. In fact, with each passing moment, the distance between the two was rapidly closing.
