Have it show a counter for how much damage there is left to be prevented. Currently it just shows up in the global effects bar without any info on duration or prevented damage. I know the rune still won't see much play, but this could maybe be worked into a QoL buff for other conditions of this type, such as Bubble of Protection, Buffer, Nora Shield, etc.
ipox likes it in the occasional trick deck, helps him hold off the rush while he pulls off his combo's
