I think my friend and I are the only ones on the server that don't have one of these lol. According to YG, this is offered as a Necro 30 leve reward, but this has never been offered to either one of us for literally months. Another YG post indicated they got it from a leve chest, not a straight-up reward.
Can anyone help regarding how this is currently obtained? Based on the YG prices I'm seeing for this, it certainly doesn't appear a very common drop.
