Energy Air Shield
Energy Air Shields are used to seal air in an area while allowing humans or animals to pass through it.
You can produce 4 Energy Air Shield with 1 Coil crystal, 4 Glowstones and 4 Basic Hull Omnipanels.
Energy Air Shields are placed next to each others to form a frame between walls. They automatically connect horizontally and vertically to seal an area, effectively stopping the air flow.
Only fluids like air are stopped by the projected shield, everything else can pass through it with no effort.
While it's possible to use Air Shields with transparent walls like glass, they are generally more efficient when used with plain/opaque walls.
