Even So..
Leonel paused, his gaze flickering.
This sounded like a top class treasure, but even without his usual thinking speed, he could already see several drawbacks to it.
For one, even if you can leave your territory, just like Pririna said, it would still be in an active state. As such, there would be a lot of things you couldn't do, like fusing new territories into it or beginning to spawn newer and more powerful beasts.
This treasure was probably best used as an escape measure to leave the territories of others if you accidentally ran into an opponent far more powerful than yourself. If you used it to escape your own territory, you would always have to come back to it eventually and deal with the enemy you left behind. So, unless you found a powerful treasure on the outside, the end result would be the same. However, considering how rare those were, Leonel wouldn't hold his breath.
