|An ivory-like quick blade that looks like it could have been crafted from the tooth of some enormous predatory creature. It is lethally vampiric, and restores a greater portion of life to its user than other vampiric weapons.|
the +12 Vampire's Tooth
+12 quick blade
This weapon always heals its wielder for the full damage it does when the vampiric effect is triggered against a susceptible target.
The Vampire's Tooth is the most highly enchanted quick blade possible, making it fairly effective for fighting even enemies that aren't susceptible to its vampiric effects; of course, it truly shines when used in areas full of natural creatures that it can suck HP from. Like all Short Blades, it can fall short when used against enemies with particularly high AC even with its prodigious enchantment, though a potion of might and/or a source of slaying can help it punch through even the toughest armour.
Stabbing specialists in particular can make excellent use of this weapon, as not only will it deal grievous damage to stab-able enemies, but it will also heal you for the full stab damage whenever the vampirism triggers. This can work particularly well if you have a means of setting up a stab mid-fight (throwing nets, a wand of paralysis, Hexes, Invisibility, etc.), allowing you to quickly heal up from any beatings you've taken thus far.
The Vampire's Tooth can be found in a vault guarded by depth-dependent vampiric monsters (ranging from vampire bats to tyrant leeches to vampires and vampire knights). This vault can appear early in the Dungeon, potentially giving players access to a quick blade well before they would normally begin to appear.
Prior to version 0.22, the Vampire's Tooth was a +4 dagger.
