The tilable Sublimate Design I implemented in many a mission on Erekir.
Resources: 16 Graphite and 20 Beryllium for junctions and router, and 200 Silicon, 400 Beryllium, 150 Tungsten, and 40 Oxide per Sublimate.
Uses Ozone for ammunition, or the more expensive Cyanogen for extra range and damage.
Note: THIS IS NOT FOR SERPULO! THIS IS AN EREKIR DESIGN!
