When Zac approached Megan and Sabelio, he found the two exchanging attacks without rest.
Megan was using her dagger while Sabelio controlled the umbra around him to protect himself and shoot out spells.
The old man's umbra control wasn't as refined as Dante's, but it was still enough to halt Megan's blade from reaching him.
Zac noticed that Sabelio was only using the "shadow bolt" spell, which he had seen Dante use before, and knew that it was meant to be a low-rank spell.
He was a bit more afraid at first since Sabelio was a forged warlock, so he didn't know if the old man would cast the overwhelmingly powerful spells that Dante used. Still, seeing that he was solely relying on shadow bolts made him relieved.
As Megan and Sabelio kept releasing a barrage of attacks that were almost too quick to see, the redhead waited for the perfect opening.
