From Sagarmatha, Discord 26/11/2023:
For level scaled items such as those found in the Adventurer's coffers for end game, the armour value is missing in the Scaling tab. Need this for updating the wiki pages. Also, items from these coffers can give up to two levels higher of the shown level. For example, "Item Level: 510+" can give you an item of levels 510, 511 or 512. The level scaling only goes to 510.
