Don't worry.
*BOOOOMM*
With that huge explosion, the Fort Walls were burst open.
The Deathspikes or any other Trap that requires Mana to activate is usually connected to the Walls, once the walls are destroyed, all traps are disabled.
This was the reason why the walls are valued so much. They are the first and the strongest layer of defence in any fort.
And now that the Woods Dynasty's Army has broken through the walls,
"Soldiers!
March Forward and Kill all these bastards!"
Ember, the General was ready to destroy her enemies with her dominant force.
"YEAHHHHH!!!"
The rest of the Squads, who were eagerly waiting for the time to shine roared in excitement and rushed forward.
While the other squads rushed towards the Fort, The Piercing Flame Squad and Absolute Earth Squad turned around and rushed back to safety.
