Brandish

Syntax: brandish - for a staff you are holding
Syntax: quaff <potion> - for a potion in your inventory
Syntax: recite <scroll> <target> - for a scroll in your inventory
Syntax: zap [target] - for a wand in your inventory

BRANDISH brandishes a magical staff. QUAFF quaffs a magical potion (as opposed
to DRINK, which drinks mundane liquids). RECITE recites a magical scroll; the
<target> is optional, depending on the nature of the scroll. ZAP zaps a
magical wand at a target. If the target is not specified, and you are fighting
someone, then that character is used for a target.

You must HOLD a wand or a staff before using BRANDISH or ZAP.

All of these commands use up their objects. Potions and scrolls have a single
charge. Wands and staves have multiple charges. When a magical object has no
more charges, it will be consumed.
