Smashing Relics is a Treasure Hunter promotion originally released in May 2017. During the promotion, players can obtain ancient relics from Treasure Hunter, but two of them can also be obtained daily on members' worlds for non-ironmen.
The relics can contain items that were originally discontinued from the Squeal of Fortune, such as the coin of balance or a TzHaar whip, along with experience-related items. A full list of rewards can be found here.
Since the promotion on 16 July 2020, players have the ability to choose each prize from three choices. The first choice can be an ancient relic prize while the two other ones are always regular prizes of the same rarity as the first.
