Drop an item (d)
This drops an item from your inventory or equipment onto the dungeon floor. If the floor spot you are standing on already has an object in it, Angband will attempt to drop the item onto an adjacent space. Be warned that if the floor is full and you attempt to drop something, it may disappear and be destroyed. Doors and traps are considered objects for the purpose of determining if the space is occupied. This command may take a quantity, and takes some energy.
