I got the same shield: 0% chance to block 0 damage but 55% percing resistance and 5% chance of 104% damages resistance.
I keep it for the look and the percing resistance.
Mostal, I talk to you earlier about this shield. If there a way to add % chance to block x damage on it, and maybe, give it a name like "Lilith shield" or "Evil shield"
I like to use "Visions of death" on Boss !! Add fear and fumble resistance but, not to much !!
