Forerunner armor capabilities 2

I was awake again, looking down from a transparent platform—perhaps the flagship of the Master Builder—upon the wreckage of a city. The light came from an horrific plasma ball rising on the horizon, shooting forth subsidiary streams of matter pattern interference—mass converting into both electromagnetic radiation and vacuum energy. Shields darkened, but not before I felt another tingle and was temporarily blinded.

My armor would have a real job to do after all this to repair the radiation damage.
