Statue of Experience - depending on the time the owner spends in the estate, it can increase/decrease experience obtained in battle.
Structure can increase/decrease the amount of experience obtained by players in battle by 50% and more, although no more than the daily norm, which depends on the building level.
Accumulation of experience, which a character can later use in battles, begins after the "accumulation" button is pressed in the constructed building. To accumulate experience a character must be in the estate, regardles of whether they are in the game or not.
You can spend the accumulated energy easily: press the "use" button and pay the tax, which depends on the buildign level. Then select the mode in which the statue should operate but there is no need to press the "accumulation" button.You will receive a text in chat that the statue is in the necessary mode. Later after a battle you will receive an additional text in chat that experience has been lost or added (depending on your current mode).
