I completed the White Star adventure not 5 minutes ago and received the loot fairy pop-up. From the chest, I got two common treasures, an uncommon item, and a rare item; the club slot was a legendary item. Based on my past experience with the loot fairy, (I rarely miss an opportunity to get it), I thought the lowest rarity it could provide was uncommon (with a maximum of 2 uncommons and a minimum of 3 rares-or-better). Is it a bug, an intended change, or something caused by White Star's loot table?
It's not the first adventure we've seen where loot fairy is giving commons in first slots. Both Kobold lvl 6 adventures have that in common.
Yep it's because White Star has a special loot table (it had done similar things at other adventures with special loot tables too).
