Mugging—the Thief's KO

A thief can attempt to knock out a victim under certain circumstances by striking from behind with a blunt instrument. In order to be eligible for a mugging attack, a target must be eligible for a Backstab (see the backstab section). In addition to all restrictions governing a backstab, a thief cannot mug a victim more than twice as tall as the thief.

The eligible thief character simply makes a mugging attack instead of a normal backstab. The thief gains his +4 backstab bonus and the victim loses shield and Dexterity bonuses. If helmets are detailed in the campaign, the victim has AC 10 unless the head is protected. If the thief scores a hit, the victim must make a saving throw versus petrification or fall unconscious for 2d8 rounds. Modify the saving throw by the difference in level or hit dice between the mugger and the victim.

For example, Pwill the thief (T9) sneaks up behind the ogre sentry (4 HD). Pwill's blow is successful, so the ogre saves as a level 4 warrior. Normally he would save on a 12 or better, but the difference in Pwill's level (9) and the ogre's HD (4) modifies his necessary save to 17. However, the DM rolls a 19 for the ogre, so Pwill's attempt only makes the sentry mad. And loud.
