Water flask

The water flask is a miscellaneous item in Fallout and Fallout 2.

Fallout
The flask has the simple property of stopping "dehydration" random encounters from occurring.

Fallout 2
The player can ask Vic where he got the flask, which leads to them heading off to Vault City to see Ed the brahmin dealer for further information. Showing Ed the Vault 13 flask will place the Den, Modoc, Broken Hills, Redding, and New Reno on the world map, and give the player 500 XP. Outside of the main quest they serve little purpose.

Fallout

 * The player is given three flasks if the outdoorsman skill is tagged.
 * A large number of flasks (50 or so) can be found on the third floor of Vault 13 in the Vault's armory, but few outside of the Vault.

Fallout 2

 * At the beginning of Fallout 2 the Chosen One is given a flask from Vault 13, to assist in their search for the GECK.
 * A small number can be found in Vic's shack
