[Anton's P.O.V]
Ellie's words ignited a glimmer of hope in me. If we could discover Arthas's weakness, it would add another layer to our chances of success.
Ellie suggested, "Perhaps Arthas is most powerful when wielding his sword. Look at him, always holding the sword, as if he can't do without it. So, the sword might be his weakness. If we can take his sword, it should make dealing with him easier."
While Ellie spoke, I took the opportunity to observe Arthas. When he wasn't attacking, he kept the sword at his side, like a motionless wooden figure. However, in action, he moved agilely like a serpent.
Although it seemed unlikely to disarm Arthas of his sword, it was the only method we could think of at the moment. So, no matter what, we had to give it a try. We couldn't just wait here to die.
