The Sprite World Key open Sprite World dungeon.
The Sprite World is a low to medium-level dungeon intended for moderately powerful (level 20 unmaxed) characters. The enemies are weak and have low health but the boss can be dangerous.
The dungeon boss drops Potions of Dexterity and rarely, Potions of Defense. It is considered to be the main source of Potions of Dexterity in the game. The dungeon is also the primary source of three untiered items: the Sprite Wand, Staff of Extreme Prejudice, and Cloak of the Planewalker.
Entrances to the Sprite World are commonly dropped from Sprite Children, which spawn from Sprite Gods. Because each Sprite God has several Sprite Children, this dungeon is one of the most commonly found in the game.
This dungeon must be completed to earn the ‘Tunnel Rat’ fame bonus.
