Holy Water

Holy water is an item added to Fallout 3 in the add-on Broken Steel. It is produced by Mother Curie III by irradiating aqua pura.

Obtaining

 * After Rosa gives Holy Water to Micky, she will give one bottle to the player. She has one more in her inventory. An additional one can be stolen from the beggar at this time, by picking his pocket after Rosa gives him the bottle but before he drinks it.
 * On first meeting Brother Gerard he will hand the player a bottle. He has two to four more bottles in inventory, which can be pickpocketed.
 * An infinite number can be obtained from Brother Gerard using an exploit. Drop all holy water and speak to him again, and he will hand over another bottle. (This stops working after the first time the player drinks any, because that triggers the next step in Gerard's conversation script.)

Bugs

 * Sometimes a message will report "Holy water has worn off," similar to the message after drinking Aqua Pura. This may repeat at intervals indefinitely. There appears to be no ill effect, except annoyance.

Behind the Scenes

 * "Mother Curie" is a reference to Marie Curie, the famous polish scientist who studied radiation and radioactive materials.
