It's a tier 4 active weapon item. It gives you +8% bullet resilience and +8% spirit resilience. When activated, it would soak up all the taken damage and applied 90% of it to you after 5 seconds, after which it would go on a 80s cooldown.
It's a survival item, for example it would be built on ivy if she is struggling. Escaping from a fight, using this item and then stone forming after the duration to avoid the excess damage would mean she would get 5 seconds of invulnerability every 80 seconds. Same with characters like wraith or any other character who can get I-frames. It's also a weapon item instead of vitality because it would be built on gun characters which are already mostly squishy. There wouldn't really be a point in building it on tanks like Abrams or Billy because other items just give much more value. Also characters with lots of actives would much rather pass on this item making it really powerful but with it being a good active and a pretty lame stat buff it wouldn't replace many actives in other builds while still seeing use.
