Information
The first bread-and-butter trap that a war mage learns to create, the floor spikes are the perfect tool for thinning out the invading orc mob. With oiled steel blades, a sensitive pressure trigger for maximum foot penetration, and a self-cleaning mechanism, this trap provides hours of orc-skewering enjoyment with minimal maintenance.
