This is just a curiosity, as I don't need any more of this item.
In a world of 2614 days and having faced it countless times (including with Winter Feast activated), I only obtained 3 Krampus Sacks.
Sometimes I think the percentage is more like the 1% rate than the 10%.
Wouldn't it be interesting to rework Klaus in ENRAGED form to guarantee this item or at least increase the rate to 50%?
