Orb of Horizons

Orb of Horizons is a currency item that can be used to reforge a map into another map of the same tier.

Spending

This orb will transform a map item into another map item of the same tier. Any rarity (except unique) and quality the map had will be retained, but its base item type and explicit modifiers (in the case of magic or higher rarity) will be rerolled. An Orb of Horizons doesn't obey the player's Atlas of Worlds rules, which means that the resulting map may not be unlocked yet.

Since Elder-influenced map (including map occupied by Elder Guardians) are coded as implicit mod, using Orb of Horizons will NOT remove the influence. Also, using the orb on Shaper Guardians Map will rotate the map to another Shaper Guardians Map, and retaining the implicit Area is influenced by The Shaper.

Currently, the orb only reroll map into map that naturally in that tier. For example, the lowest tier of Scriptorium Map and Sepulchre Map are T6 (as of 3.12 patch). Thus, rerolling any T6 map will result in either Scriptorium or Sepulchre . GGG has confirmed it is intended and not a bug.1
