This mix is made by using Caviar on an Antifire (2). When used in conjunction with an anti-dragon shield it will provide complete immunity against dragon fire for exactly 6 minutes. Players will get a warning in their chatbox 5 minutes after drinking a dose, saying: Your resistance to dragonfire is about to run out A minute later another message will sound after the initial warning: Your resistance to dragonfire has run out.
With sounds on, players will hear a sound similar to the retribution prayer when it wears off. This allows you to keep track of how long you have until you have to drink again.
