Effect: A vorpal weapon can instantly kill most kinds of creatures. On an attack roll of a natural 20 which is also confirmed as a critical hit, and if the enemy has 1000 or fewer HP, the enemy's "head is cut off".
There's no special animation shown on a successful vorpal. Aside from a blueish coloration that appears, the monster simply dies.
If the enemy has more than 1000 HP, or is otherwise immune to instant kills (e.g., red- or purple-named enemies) they instead take 100 points of bane damage.
Some items may have a stacking effect which is produced in the event of a vorpal roll, such as Vulkoor's Cunning, and Shocking Blow on Charged Gauntlets.
These creatures are immune to vorpal's instant death or bane damage, generally because they do not have a head, or do not need a head to survive:
Undead (except vampires)
Constructs (except Warforged)
Beholders
Oozes
Also, the Deathblock and Deathward effects prevent vorpal. Fortification, however, does not.
[edit]Trivia
The term comes from "Jabberwocky," the famous poem by Lewis Carroll, where a hero has a special sword that severs his enemy's head with a "snicker-snack" sound.
Not-so-incidentally, Kasquick the Mighty, a fearsome kobold general in The Shroud, attacks with a vorpal blade that, if he is successful in attacking you, shows gruesome messages in your Combat log:
(Combat) You are hit by Kasquick the Mighty's vorpal.
(Combat) Snick-snack went the vorpal blade, and it removed your head, killing you instantly.
