— In-game description[src]
The Reduction Bomb is a purchasable power-up via ThiefNet in Sly 2: Band of Thieves and Sly 3: Honor Among Thieves. While the Reduction Bomb power-up doesn't appear in Sly Cooper: Thieves in Time, a similar power-up, Shrink Ammo, does.
The Reduction Bomb allows Bentley to drop a bomb that shrinks any guard in its range to 25% of the original size. Afterwards, any of the small guard's attacks will be weaker, (though they can still knockback Bentley) and a single hit from Bentley will kill the guard in most cases. If an affected guard is not disposed of quickly, the guard will eventually return to its normal size.
In Sly 2 and Sly 3, you have to assign a button to the Gadget Grid (either , , or ) in order to use a reduction bomb. Bentley holds the bomb like normal (in his hand in Sly 2 or in a mechanical arm in front of him in Sly 3) and the assigned button has to be held down. A green aura surrounds the bomb. When dropped, you can see the bomb's radius is wider than a typical bomb. Each use drains energy from the Gadget Meter.
- Using this bomb on Carmelita in Sly 3 allows her to be killed, though she does not disappear. She will lay on the ground, and eventually return to normal size.
