To remove this shield, use Light based damage up to proc - Lux (Swipe/Lunge), Trueflight, Flash Nova, Retinal Gaze, and Light Skillchains all work well. A critical attack from someone /thf works much more reliably and faster.
Appears to take additional (50%?) damage from light based attacks.
Seems to become stronger during full moon moon phase.
