You'll need to tell the barkeepers that you're doing the bar crawl and they will give you what you need. The brews are very strong, though, causing some damage as well as some steep temporary drops in stats. The entire trip will cost around 210 coins, plus money for runes/tablets and boat trips to Karamja. Once you have every line of the card signed, return it to one of the guards at the Barbarian Outpost .
