Lost Laboratory

Lost Laboratory is unlocked through normal game play when a player reaches level 155.

Lost Laboratory was introduced during the Forgotten Story Update. It is the only Picture added to the game by this Update that was not involved in a Timed Challenge Event.

From the Diary:

"Apparently there was once an alchemy laboratory in the Mansion. It disappeared after the Mansion reconstruction, long before Richard. Who was the mysterious alchemist and what did he work on? I hope I'll find answers in the only remaining photo."

Lost Laboratory is one of the pictures in the game that does not reward any combining elements, but does reward collection items that require a large number of combining elements to combine.

Resource Demands and Rewards for Playing[]

Lost Laboratory is a Collection Item only Picture. This means its list of potential rewards for each play only contains regular Collection Items, mode dependent Collection Items (depending on what mode the Picture is currently in), and Quest Items (if a Quest is currently active for the Picture). The list of potential rewards for Lost Laboratory is made up of 11 Collections:

When Lost Laboratory is first opened, it is at Novice level, and only the items from the Egyptian statuettes collection will be on the list of potential rewards. As the level of the Picture is increased, more and more items will be unlocked as potential rewards.

The amount of energy required to play Lost Laboratory will increase as the level of the Picture is increased. The experience points and coins rewards for each win of the Picture will also increase to match the increase in resource demands:
