Legacy of Nightmares

Legacy of Nightmares (named Legacy of Wicked Dreams pre-Reaper of Souls) is a minor item set in Diablo III. Both pieces require a character level of 60 to drop.

In Season 17, all characters have this bonus for free, as long as they have no others (does not stack with the LoN itself).

In patch 2.6.6, a Legendary Gem with a similar bonus has been added: Legacy of Dreams.

Pieces

 * Litany of the Undaunted (Ring)
 * The Wailing Host (Ring)

Set Bonus (2 items):
 * While this is the only item Set Bonus the character has, their damage dealt is increased by 750% and damage taken is reduced by 4% for every Ancient Item they have equipped.

Development
Original set bonus of this set (pre-2.4) was significantly different: The last bonus had a small (roughly 10%) chance to trigger, and a 15 seconds duration with no internal cooldown. There was no cap of how many Skeletons can be summoned at a time.
 * 15% extra gold from monsters
 * 15% better chance of finding magical items
 * Will sometimes summon a Skeleton or Skeleton Archer when you attack.

At early stages of 2.4 testing, the bonus for an Ancient item was as high as 800% damage.
