Paralyzing Palm (Fallout 3)

Paralyzing Palm is a perk in Fallout 3, Fallout: New Vegas, and Fallout 2d20.

Fallout 3 and Fallout: New Vegas
With Paralyzing Palm, you have a 30% chance to paralyze your target for 30 seconds with an Unarmed V.A.T.S. attack. This does not interrupt the V.A.T.S. sequence, cost any additional AP, or change damage compared to the original attack.

In Fallout: New Vegas, this perk essentially allows a character to do a more powerful version of the Ranger Takedown inside V.A.T.S., as Ranger Takedown can only be done outside of V.A.T.S.

Bugs

 * Attacking a paralyzed enemy with an Unarmed weapon can be difficult at times. The hitbox that determines where the target can be attacked for damage can sometimes disappear altogether. Attacking such a bugged creature will result in specks of dust coming off it with a dull thud sound, as if the player were attacking a wall.
 * If an enemy is paralyzed, and then shot with a Gauss rifle using a second V.A.T.S. attack, there is a chance the enemy will fly off into the distance from the knock back of the Gauss rifle.
 * It seems to be impossible to paralyze ED-E using paralyzing punches, as they'll never trigger when attacking him.

Fallout 2d20
When in combat, attacking an enemy performing the aim action to hit a specific body part adds the stun effect. The attack must be done with a weapon using the unarmed skill.
