• TerraFortress: "Terra" (earth) and "fortress," evoking an earth-based, impenetrable defense.
• Aeroblast Shield: "Aero" (air) and "blast shield," suggesting air-based force field attacks and defenses.
• Magma Bulwark: Combining "magma" (fiery earth) with "bulwark" (a strong defense).
• Glacial Bastion: "Glacial" (ice) and "bastion" (a strong defensive structure).
• Stormwall: A simple but evocative name combining storm power with a defensive wall.
• Elemental Guardian: A more generic but effective name highlighting both aspects.
• Chthonic Rampart: "Chthonic" (relating to the underworld, suggesting earth power) and "rampart" (a defensive wall).
• Aetherium Defender: "Aetherium" (suggesting a powerful, ethereal energy) and "defender."

Emphasizing Force Shield:
