Something that isn't (really) covered in the diary, however, is a somewhat important detail that is best illustrated by the in-game tutorial popup: As the highlighted section suggest, you can run a featured instance once per day at lvl 105 AND once per day at lvl 100-104, and get daily rewards from both! This is consistent with talk in World that there is a different reward box at 105; a crimson one, whereas at lvl 100+ (up to 104 presumably?) a grey reward box is given. Which, in turn, is consistent with this passage from the dev diary:
suggesting different boxes in order to keep the loot tables separate.From level 100 to 104, this extra reward will primarily be Scrolls of Empowerment.
As a disclaimer to the above though, empirical testing is needed to validate it.
