Trapped
Looking at the Grogal's stats, and its hunger, Arthur knew waiting would waste too much time.
'Dammit, it's at 99%. It'll take at least four or five hours for it to even reach sixty percent. The Grogal won't go out to hunt before that.' Arthur had studied the creature's behavior before and it was well documented in the forums.
This was also why the players in his past life had a hard time finding the field boss.
They only got a few hours to search the 'fixed open areas' that the Grogal would spawn in. After that, it would wander around in the entire Oxal Mountain Outskirts and one would have to rely on their luck to find it.
Thus the time needed for it to get decently hungry was also documented and they knew at what percentage the creature would hunt.
'No way I'm wasting so much time here.' Arthur didn't want to do that at all.
