DRINK allows one to consume potions, tinctures, and whatever elixirs bartenders might have in stock.
Magical drinks (this includes potions made in alchemy and herb tinctures/elixers) will follow the same rules as magical foods. Drinks cannot normally be made with Magic Item Creation (420), and spell drinks are special in that they do not require any Magic Item Use (MIU) to use. On the other hand, training in MIU does not increase the duration of a spell effect received from drinking a magical drink. Most spells of variable duration (dependent on training) last ten minutes. Spells of set duration (e.g. Celerity (506)) last the duration normal for that spell.
DRINK is also used to ingest beverages found in bars, pubs, and shops.
