Destiny 2: Forsaken had one of its best surprises yet this week with the introduction of the Shattered Throne dungeon. A strange amalgamation between a raid and a strike, the Shattered Throne is filled with puzzles and difficult boss fights. It also packs appropriate rewards, offering players three powerful pieces of loot and the quest for the Wish-Ender exotic bow. But in Thursday’s This Week at Bungie, the studio announced that the dungeon is going away — for a few weeks, at least.

In the blog post, Bungie said that the Shattered Throne will only be available every third week — as the curse upon the Dreaming City reaches its max. This may be a problem for some players who hope to get the dungeon done before the end of the week, as the recommended power for the final encounter is 590 — only 10 below Forsaken’s current max of 600.
