Perhaps the most exotic and arcane of Star God technologies, it is based on the strange 'phase-shift' effect, where something can exist in our reality, but yet, not quite so. When applied to individuals, a phase shield can make them invisible and intangible to most weapons, while perfectly able to shoot back. It still cannot fool motion scanners or psionic detection, though. When applied to a craft, the results are less spectacular, effectively amounting to a major boost of shield strength.
