Those from Sacred Beasts were taken aback by Izroth's bizarre request. He wanted to face thirty to forty players by himself?! If it were casual players, it would not be much of an issue.
However, these players knew that Sacred Beasts were one of the top ten guilds. Not to mention, they had just defeated a world boss—this alone was enough to deter most players. Either they were incredibly foolish, or their overall skill level was above that of a casual player's.
Even if Izroth was skilled, the members of Sacred Beasts had seen him use at least three to four high-ranked skills. As a combat master, they understood how challenging it was to learn one high-ranked skill, let alone three or four. To them, that was already a miracle and major accomplishment. That's why they believed that Izroth had exhausted his strongest skills fighting against the Failed Chimera. Since that was the case, how could he possibly take them on by himself?
