I slam my staff on the ground and create sharp tree roots from the wall to stab the last group of traitors on the wall. We manage to clean the left side of the wall out of the traitors that try to kill us. We manage to kill them before they can do much damage to my unit.
The other unit is not so fortunate. If not for me constantly releasing an AOE healing spell, more would be dead. Sadly, I have a range limit, and even when I was already casting [Ultimate Magic: Star of the Beginning], it was not enough, as my ultimate magic lasted only twenty seconds long.
It takes us almost half an hour before we manage to retake control of the fortress. Now I can focus on the battlefield outside the wall.
