5150: Star Army has a unique mechanic for flamers and plasma weapons. Each shot lays down a 1" wide path that ends in a 3 inch circle. The attack creates a persistent table effect that can be used to slow down enemies or weaken a few bugs.
The set contains a 3" circle with a 2" etched circle for use as a template for other area effect weapons. The 9 extensions allows you to use as many as you need up to a maximum of 12". The final piece provides a flat end cap for the template.
