Both sides clashed in the middle again. The heroes managed to get the upper hand, killing four villains, while their healer and melee damage survived.
They chased the last villain to his tower and killed him there. Under the barrage of arrows from the tower and the villain soldiers, the hero damage dealer stayed calm and focused his attacks on the tower while the healer slowed the rate that his health was falling.
The villain's first tower fell, giving the hero team enough upgrade points to gain two levels.
Before the melee hero died, he killed the last of the villain soldiers.
The second upgrade increased the damage that the arrow towers did. With the third upgrade, Lucan was provided with a choice.
He could upgrade the ammunition the arrow towers used, he could upgrade the strength of the defensive barrier around the core, or he could upgrade the soldiers.
