Repellent Stick

The  is a unique quest-related melee weapon found in Fallout 3 designed to ward off Mole Rats, though it unintentionally has a far more fatal effect on them. It is a simple stick, the tip of which is soaked with an unknown green chemical compound created by Moira Brown in her lab.

Location
This item is obtained from Moira Brown at Craterside Supply in Megaton.

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. Moira will exclaim "Poor little mole ratties!" when she realizes it does more than chasing the Mole Rats away.

Bugs

 * Because it is a quest item, if you convince Moira Brown to give up on the book, buy it back from her, or pick the lock on her desk and take it after completing the quest, you are unable to drop it.
