The Secluded Thicket Key open Secluded Thicket dungeon.
The Secluded Thicket is a dungeon designed by Toastrz which is heavily based off of the Forbidden Jungle, in a similar vein to the previous “Epic” dungeons.
This dungeon drops from the Court of Oryx, and is the 5th Court dungeon to be introduced (4th if you exclude the event-exclusive Ice Tomb). As with the other Court dungeons, it consists solely of the boss. However, this dungeon takes an alternative approach to the format and instead the dungeon is divided into three boss fights.
This dungeon is a source of Attack/Defense Potions (first boss), Mana Potions (second boss), and Life Potions (third boss), along with a number of Untiered items.
