Old School RuneScape uses the British convention for floor numbering: Ground floor, first floor, etc.

Chocolate dust is made by using a knife or a pestle and mortar with a chocolate bar. It can also be obtained by bringing Wesley in Nardah noted chocolate bars, who will crush them for you for a fee of 50 coins per item. Chocolate dust can be bought from Hudo at the Grand tree.
It is used for making energy potions in Herblore, chocolate cake for food or chef's delight by brewing.
