The eight-hundred Expert Mages that joined the frontline were quite capable. They were very useful on the count that Timothy and his team spent a few hours nudging them in the right direction, and once they got a hang of what to do, there was no stopping them!
Ten more shapeshifted Ancient Sea Orcs had tried to attack the city before sunset, and the Expert Mages, otherwise known as the city's soldiers, had killed them all! They killed them without losing a single man or woman in the exchange of attacks.
They discovered that the giant orcs had this odd ability to toss exploding fireballs around almost randomly, but they worked around it. Ten mages shot fireballs at the giants to overwhelm them, essentially blind them, and then twenty mages snuck below the line of fire, and froze the giants solid! This method worked like a charm, and Timothy had helped them develop it, so the mages didn't lose arms and legs during their many fights.
