After reviewing the Butterfly Fairy's skills, Ethan turned to the others and said, "Stay back. If I get controlled, you all might be done for."
The Butterfly Fairy Charm skill is really nasty—it's invisible and nearly impossible to dodge. If he gets charmed, his only escape would be to use Void, but Void's cooldown is far longer than Charm's. If she lands the Charm while Void is still on cooldown and forces him to attack Luna and the others, he'd drop each of them with a single swing—nothing would stand a chance. This is no trivial threat.
Luna and Zephyr had already reached level 25, allowing them to view the boss's stats. Naturally, they understood what Ethan meant. They quickly led the others away—this wasn't a joke. Sealed was far more terrifying than the boss itself.
