The Arc Field is a Titan defensive ability utilised exclusively by the Arc Titan in Frontier Defense. Due to the field's exclusivity to the NPC Titan class, it is unobtainable by players. The Arc Field takes the form of an electrical field surrounding the Titan that heavily damages enemy infantry, Titans and structures (such as the Harvester), in a manner similar to the Electric Smoke. This ability is extremely effective at stripping shields and killing Pilots who attempt to Rodeo. Due to this, it is recommended to engage Titans utilising the Arc Field at range.
