Icebrew's Secret Recipe  

Bartender Icebrew has a secret recipe that makes his drinks so special. He uses rust monster blood from Rust Monsters in the Sunken City. He can craft you some, but he happens to be out of Rust Monster Blood.

Kill Rust Monsters in the Sunken City to attain 10 bloods then return to Bartender Icebrew.

He will reward you with an Icebrew Belt and 5 What Rust Stouts.

This will also open up the Blind Taste Test quest.
