When harvested, 60% of the energy you obtain will be from your highest tier, 30% will be from the tier below and 10% will be from two tiers below e.g. 60% Incandescent, 30% Luminous and 10% Radiant at level 95+ Divination.
In addition to energy, you can also obtain Portents of restoration VII, Portents of restoration VIII, Signs of porter IV, Signs of item protection and Signs of life.
If other players harvest from a simulacrum you have placed, there is a chance that you will obtain noted signs and portents.
Once placed, the simulacrum will last for 5 minutes if not interacted with. Once interacted with, it will last for roughly 30 seconds.
You may only craft one divine location per day, but you may place as many as you like.
