Upgrade your Weapon to the Max for Orcs Must Die 3

Upgrade your Weapon to the Max

Regardless of how many traps you have placed, the key to victory in the majority of the rounds will be your weapon. It is therefore important that you continually upgrade it whenever possible, so it is at it's maximum potential. Your weapon can be used to thin out attacking waves of opponents early on and stop enemies breaking through before they even reach the rift.
