Bestowing Negative Levels with Magic Weapons

[Corwin of Amber]

I am currently wielding Souldrinker (I am immune to energy drain) and I would like to further enhance it to bestow negative levels. I am aware of the Souldrinking property from BoVD, but I would like to know if there are any other, similar enhancements.

You mean Life-Drinker?

This +1 greataxe is favored by undead and constructs, who do not suffer its drawback. A life-drinker bestows two negative levels on its target whenever it deals damage, just as if its target had been struck by an undead creature. One day after being struck, subjects must make a DC 16 Fortitude save for each negative level or lose a character level.

Each time a life-drinker deals damage to a foe, it also bestows one negative level on the wielder. Any negative level gained by the wielder in this fashion lasts for 1 hour.

Strong necromancy; CL 13th; Craft Magic Arms and Armor, enervation; Price 40,320 gp; Cost 20,320 gp + 1,600 XP.

Adding extra abilities to specific item is a rules grey area. I generally recommend pricing upgrades to the item by first rounding up to the next plus, then charge as if upgrading an item of that price.

Example: Issac's Boot, the +1 plate boot that deals double damage to undead who are prone, has a price of 16k, about the price of a +3 weapon, 18k. IMHO making it a +2 plate boot should make the price 30k since 14,000 gp is the price difference between +3 and +4.

Lifedrinker's cost is close to a +5 weapon [50k] and exactly that cost if one decides Lifedrinker's liabilities* qualify for a 20% discount.

Best vampiric boost for a weapon I can think of is Bodyfeeder

Bodyfeeder
All feeder weapons have a special ability that functions only upon scoring a successful critical hit. A bodyfeeder weapon grants its wielder temporary hit points equal to the total damage dealt by a successful critical hit. These temporary hit points last for 10 minutes. Thus, if the wielder of a bodyfeeder weapon successfully scores a critical hit while the wielder still enjoys temporary hit points from a previous critical hit, the wielder gains only the better of the two values: either his current number of temporary hit points, or the new influx of temporary hit points, whichever is higher.

Strong psychometabolism; ML 12th; Craft Psionic Arms and Armor, claws of the vampire; Price +3 bonus.

Bodyfeeder seems like it won't happen enough, but you score a critical hit every time you...

Coup de Grace...

...You automatically hit and score a critical hit.

... against a helpless foe.

Get an ability to bestow touch spells by weapon (iirc spellsword and/or duskblade have it) and then hit them with enervation (though i prefer vampiric touch)

What's your character?

Duskblade cannot channel ray spells like enervation.

I am a Human/Necropolitan Cleric 9/Ordained Champion of Wee Jas 5.
I currently have channeling from the Ordained Champion, but Clerics do not have enervation as a spell.
