Spending
Regal Orbs do two things when used on an item: they add an additional affix, and they convert a magic item into a rare item. Regal Orbs can only be used on magic items.
The adding an affix is useful for improving Maps or Strongboxes, where additional affixes can yield additional results.
Converting a magic item to a rare is important for crafting in that a rare item has space for six affixes (three prefixes and three suffixes) while a magic item only has space for two affixes (one prefix and one suffix).
In crafting, using a Regal Orb is a middle step when crafting a magic item with good affix(s) into a rare. If the affix added by the Regal Orb is desired, one can continue adding up to a total of six affixes through master crafting (using the Can have multiple crafted mods suffix) or the use of Exalted OrbsExalted OrbStack Size: 20Augments a rare item with a new random modifierRight click this item then left click a rare item to apply it.

If the affix is not desirable, an Orb of AnnulmentOrb of AnnulmentStack Size: 20Removes a random modifier from an itemRight click this item then left click on a magic or rare item to apply it. can be used to randomly remove an affix (hopefully the undesirable one).
Lastly, Regal Orbs can be used to purchase certain skill gems from vendors.
