Hunter's Ale

Hunter's Ale is received after completing the Bear Hunters quest in Fort Ranik (Pre-Searing) or from collectors in Cantha. The brew reputably causes the screen to temporarily blur and erratically zoom in and out. Hunter's Ale only known practical use is to acquire the drunkard title. It cannot be salvaged. Beware drinking several tankards in rapid succession. This may result in a loss of balance, and inhibitions. In Factions, Hunter's Ale has become an item that can be received from collectors for Imperial Commendations, Monastery Credits, Luxon Totems, and Equipment Requisitions with the same effect.

Currently the only use for Dwarven Ale is to get the Drunkard title.

Levels of drunkenness
There are 6 levels of drunkenness distinguishable when dealing with Hunters Ale. When you did not drink any kind of alcohol you are at level 0. For each ale drunk in a row you ascend one level until you reach the highest level. After that drinking ale has no effect besides the waste of money. Every minute you will automatically descent one level until you reach level 0. With every descent you will earn 1 minute towards Drunkard title.

As you can see it is most efficient to stay within level 2 and 5 to gain the Drunkard title. E.g. you could drink 5 ales in a row then wait for 3 minutes so that you drop to level 2. Then you have to drink another 3 ales to get back to level 5 and so on.
