The guards were astounded by the fact that Walker had created flame dolls of Midnight. They were seemingly field by the bonfires but had made a large difference in the battle. The glacial wolves had feared them and avoided their pouncing attacks. They managed to keep the glacial wolves occupied and even light the area better for the adventurers to attack.
The blinding effect from Gil's arrow was also a huge boon for their fight. The adventurers had been able to further surprise the glacial wolves and land attacks on their legs that stopped their movements. The guardian barely had to react since the adventures jumped for the killing blow.
The only ones that had been injured were due to the wild swings of claws and bites from blinded glacial wolves. However, this only left very shallow cuts on them along with damaged armors. Beating an opponent with sense weakened was easy for the higher ranking adventurers who had years of battle experience.
