Monoliths
Monoliths are static devices in the Reclamation Algorithm game mode of Arknights.
Monoliths act as a source of 
Stone and harvested by having friendly units attack it, who attacks enemies over the Monoliths, until their HP is depleted, at which the Monoliths' HP is fully restored and it will have 1 that can be picked up by deploying an Operator adjacent to it, adding the Stone to their carry capacity which is equal to the Operator's block count and will be accounted for when the Operator is retreated. After the Monoliths is harvested a certain amount of times, it will be exhausted and cannot be gathered from anymore (although the Stone it has can still be picked up).
Basic Harvesters deployed from Advanced Gathering Hubs are more effective in harvesting Stone from Monoliths than other resources.
