Units that have an item from the Items data type in their Stats: Item field become able to be picked up by Inventory type abilities and gain the Item status flag. When in an inventory or associated Container, the item unit gains the Hidden flag and gives the holding unit the bonuses of the item if the slot of the inventory that the item is in permits it. When in the inventory or container, the item may give abilities, behaviours and weapons to the carrying unit. Units inside the inventory can also interact with the carrying unit via periodic Buff on the item unit that uses a Search Area effect with 0 arc and 0 radius. This allows for validations that are not possible otherwise.
