A XP lamp (tier 5) is an item obtained during the Broken Home quest. It is the fifth lamp obtained in the quest, located in a chest found below the basement, after the puzzle with the four statues (past the Noose door), down the first flight of stairs. It cannot be obtained on the first playthrough, and requires at least level 50 in each skill. Unlike other items, it can be taken out of the mansion. However, it cannot be banked. Rubbing it gives 16,000 XP in a skill of your choice.
