Improved Grab (Ex): To use this ability, the executioner's hood must hit with its slam attack.

Suffocation (Ex): An executioner's hood that gets a hold wraps itself around the head of a Medium-size or smaller creature as a standard action. The executioner's hood attempts a grapple that does not provoke an attack of opportunity. If it gets a hold it deals damage (equal to its slam attack) per round.

A creature can hold its breath for a number of rounds equal to twice its Constitution score. After this period of time, the creature must succeed at a Constitution check (DC 10) each round (the DC increases by +1 for each success). On a failed roll, the victim falls unconscious (o hp). In the following round, the victim drops to -1 hit points and is dying. In the third round, the victim suffocates.

Attacks that hit the executioner's hood deal the same amount of damage to the victim. Spells that affect the executioner's hood have full effect on the victim as well (because the executioner's hood attaches many small fibrous strands to the victim).

Sleep Immunity (Ex): Immune to sleep effects.

Alcohol Vulnerability: Pouring wine, ale, brandy, or the like on an executioner's hood deals 1 point of damage to it per round. After the hood has taken 4 points of damage, it will release its victim and drop to the floor. At least 1 full quart must be used.

The executioner's hood will cling to a wall or ceiling awaiting its prey. When its prey passes under it, the hood drops and attempts to engulf the victim's head.
