Slippery Slope (3.5e Maneuver)

Clearly, your opponent's request inevitably leads to the end of the world.

When somebody attempts to get other intelligent creatures to do something, you may counter their request with Slippery Slope. Anyone who hears your counter will not do that thing when it is requested by that creature for the duration. If the creature was going to do it without being asked or told to, this won't stop them.
