Repellent Stick

The Repellent Stick is a wooden stick with Mole Rat Repellent on it. It is given to you by Moira Brown during the quest Wasteland Survival Guide. Upon completing the quest, if the optional objective of using the repellent on a total of ten Mole Rats is fulfilled, the player is able to keep it for future use. If the optional objective is not fulfilled, or if the quest is completed with a Speech-based lie, Moira takes back the stick but will sell it to you from that point on, meaning you can still have it permanently if you accidentally or intentionally did the bare minimum. If in the future you don't have the repellent stick and you want it, it can be found by lock picking the desk upstairs (hard). Be careful while doing this, since if you take it this way it may not be taken out of your inventory. It will be considered a quest item whether or not you completed the quest and it will permanently take up 3kg.

The stick is exceptionally effective against Mole Rats, as one hit causes an allergic reaction on Mole Rats, causing their bodies to smoke and their heads to explode in a few seconds, while a second hit will cause the explosion to happen instantly. It is also partially effective against Radroaches, as it will kill them in two hits, as well as cause their heads to explode quite frequently. It has to be said, that even your bare fist can kill Radroaches with two hits, so it's very questionable to carry 3 pounds equipment with you for nearly nothing.

 * Xbox 360: If you convince Moria Brown to give up on the book, she might not take the repellent stick back. You can not drop it because it says it's a quest item, so it wastes 3 pounds of space.
