Beard Flask is an item in Dragon Age: Origins, specific to Oghren. It requires Feastday Gifts and Pranks DLC.
It is originally a gift sold by Bodahn Feddic. It becomes a usable item after giving it to Oghren.
Oghren will drink from it and gain the "Roaring Drunk" buff (+2 strength). It is treated as an injury.
- Roaring Drunk: The booze doesn't seem to slow Oghren down--it just gets him started. Bonus to strength.
