Flour is an item that can be found in the H.A.M. Hideout, in the south-west room. It cannot be picked up normally; attempting to do so will prompt the message "I can't pick it up! I need a pot to hold it in." Using an empty pot on the the flour will create a Pot of flour.
The item can only be taken as an item with Telekinetic Grab, and it will behave as a normal item. It has none of the same uses as a pot of flour, rendering it almost completely useless. If dropped, it will behave as it did before it was taken; i.e. it cannot be taken normally, can be telegrabbed, and can be placed inside a pot.
It was previously dropped exclusively by Black Knights, but was removed after an update[ ]. It was later added back as an item in the H.A.M. Hideout when it was updated with the release of RuneScape 3.
