in the minecraft dungeons dlc trailers, the unique gear is displayed as common despite actually being unique
edit: this seems to only be in the howling peaks trailer, as jungle and nether show the correct rarity and winter shows no unique items in the inventory.
Are you referring to the videos at https://www.minecraft.net/en-us/dungeons ?
Jungle https://youtu.be/dXZgUCxF5qc
Winter https://youtu.be/bA1DxKP63hs
Peaks https://youtu.be/PC0e1-rtn-Q
Nether https://youtu.be/vAdT4Kp9nGE
I did see some for Howling Peaks video at t=19 (Goat Gear, Rugged Climbing Gear & Resolute Tempest Knife) but not for any of the others.
Could you elaborate on the others?
