“Fuck you, you bastards!” Gustav yelled out, and thrusted his arm forward, as to shoot a fireball.
During his fit of rage, he seemed to have forgotten that there was a transparent shield in front of him, so if he shot a fireball now, then all four members of the team would suffer the consequences! They could get burned into a crisp.
Ortana was aware of this, so she dismantled her transparent shield temporarily, thus allowing the fireball to pass through, and hit the amphipteres! Afterwards, she put her shield back up immediately, because in this situation, where they could barely predict what could come next, a shield was the only thing that kept them alive, and from shitting themselves.
The fireball roared forward, and hit one of the monsters. Other than getting one of them to flinch, it was fair to say that the fireball was ineffective. Now, they were officially out of ideas.
