Runecrafting & Summoning Rifts
Runecrafting & Summoning Rifts was a five-day event and Treasure Hunter promotion. It was released on 7 April 2016 and ended on 11 April, although some features would remain until 18 April. The event was open to Ironman Mode players, and free-to-play players could participate in the Runecrafting parts of the event and promotion.
There were two types of rift: A large rift, found north-east of the Draynor lodestone, and small rifts, found at various places throughout Gielinor. Small rifts gave greater amount of experience than large rifts. However, their locations varied while the large rift was always found near Draynor.
Closing rifts also earned progress toward cosmetic override rewards of Dryad Wings and Runic Essence Wings, which were unlocked separately by gaining Summoning and Runecrafting experience at the rifts, respectively.
Players had a daily amount of fatigue which limited how long they may close rifts for each day. The amount of fatigue a player had could be checked while at a rift. Consumable Rift sunderers which could be won from Treasure Hunter allowed players to close rifts without affecting their daily fatigue limit.
The main part of the event ended on 11 April. After this time, players would no longer be able to win more rift sunderers from Treasure Hunter and Small Rifts would not spawn. However, players would be able to use any previously obtained rift sunderers at the Large Rift, which would remain until 18 April.
