Paralyzing Palm (Fallout: New Vegas)

Paralyzing Palm is a perk in Fallout: New Vegas.

Effects
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.
 * It seems to be impossible to paralyze ED-E using paralyzing punches, as they'll never trigger when attacking him.
