Repellent Stick

The  is a unique quest-related melee weapon found in Fallout 3 designed to ward off Mole Rats. It is a simple stick soaked with an unusual, green substance at the tip.

Location
It is given to you by Moira Brown during the quest Wasteland Survival Guide.

Characteristics
The Repellent Stick is a simple wooden stick with Mole Rat repellent on it. 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. Do not be fooled by what Moira says when you first get this stick, as it's an experiment gone wrong.


 * The repellent may actually be a modified form of the FEV, noted by it's strange "cranial combustion" effect on mole rats.

Bugs

 * Xbox 360 and PC: If you convince Moira 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. But, If you answer her question about how the stick worked using charisma you will be able to keep the stick as a normal object.
 * Newly discovered. All undroppable quest items, despite what the game says they weigh, weigh nothing. Tested by dropping all dropable equipment and having 20 pounds worth of quest items.
 * PS3 & Xbox 360: If you pick the lock on her desk, there is a repellent stick. If you take it when you have already finished the quest, you cannot drop it because it's a quest item, taking up 3 pounds of space.


 * PS3 & Xbox 360: It is possible to buy the repellent stick back from Moira directly after giving it back following completion of the quest, without completing the optional objective. The stick appears in her inventory. However, once you buy it, it is treated as a quest item and can not be dropped or removed from your inventory, it will not take up any weight in your inventory, but you still can not remove it.


 * Because it's a quest item, if you enter the Operation: Anchorage simulation before you complete the Repellent Stick quest, you will keep the stick in your inventory even after everything else is taken away.
