The Wall Blades are a wall trap, unlocked in the level Lunch Break. They have a very small range but high damage output. The range is approximately 1 square out from the trap but with it's fast attack it can quickly remove a group of orcs. Keep in mind the attack is very quick so make sure as many enemies as possible are in range when it does activate.
Upgrading the Wall Blades increases the damage they do to enemies.
