"Just do what you can." Amy said before she cast a buff on the rest of them.
There was no need for her to buff him yet since he wasn't struggling.
The only way that they could help was to try to reach his level so that they would be able to hold back a few of the demons.
Andrea looked down at her sword before charging forward like Gran Jurad did, but she was slower than him and she didn't have the same power as the hero's sword.
In the end, Andrea wasn't able to push through the demons like Gran Jurad did.
If it wasn't for the fact that Amy had buffed her, then she would have been trapped by the demons and would have been overpowered by them.
There was a reason why the demons were able to push the humans back so far.
Individually, the demons were stronger than humans.
So when they were working together like this, they were naturally stronger than what a single human could do.
But since she was able to stop them, Andrea was able to keep them back away from Gran Jurad.
