Empty Flask

An empty flask can be used to collect lots of different things. To collect a sample of something, equip the empty flask in one hand and then click to 'wave' the flask over what is to be collected.

You will receive an empty flask after drinking a potion. Contents of flasks can be consumed, thrown and sometimes applied to other objects (e.g. wyrd water, oil, etc.)

For more info about what can be collected in an empty flask, read Potions page.
 * Bug: Some times the game does not give you a empty flask after using a potion. To avoid this is best to move the potion around in the inventory around and have free space before using it.
 * Trick: Can be throw at enemies to push them a little or to block arrows or potions that have been throw at you, though any other item can be throw too to get the same effect.
