All for one

3.5
ok, so in many forms of phantasy media there is one really common trope of the BBEG having the ability to steal/siphon powers or magic or essence or what not. so my question is basically if there were any official materials of something actually being capable of this either threw magic, race, template, etc.

(P.S. I'm a bit of a noob and have only played the game for about a year so if this is something obvious, please forgive my ignorance)

thanks for all the help in advance, and i wish you all luck in the playground :smallwink:

Spell thief kinda does this to spellcasters vy stealing their spells. But it isn't very good at it.

Barghest in the Monster Manual.
Redcap in Monster Manual III.
Dusk Giant in Heroes of Horror.
Illithid Savant prestige class in Savage Species.
I'm sure there are plenty more.

The spell "Ability Rip" seems fitting for this

Ability Rip
(Serpent Kingdoms)

Transmutation
Level: Sorcerer 7, Wizard 7,
Components: V, S, M,
Casting Time: 1 hour
Range: Touch
Target: Two living creatures
Duration: 1 hour/level
Saving Throw: Fortitude negates (see text)
Spell Resistance: Yes

You rip a supernatural ability of your choice away from one creature and transfer it to another.

The two creatures must be within 30 feet of each other and remain conscious throughout the casting of the spell. In exchange for this new ability, the recipient permanently loses a supernatural ability it already possesses. If it has none to exchange, it instead loses two class levels (or 2 Hit Dice if it has no class levels).

Class features cannot be transferred by means of this spell.

The spell fails if used to transfer an ability to a creature that lacks the proper body parts, size, or other criterion for its use, or if the target creature has fewer than 2 Hit Dice and no supernatural abilities to trade. Either subject may negate the transfer with a successful Fortitude save.

Material Component: A caterpillar in a cocoon.

Transfusion spell from Dragon Mag for ability scores

Are you DM or player? If DM you should just homebrew the effect you want.

Aura of Tyranny (stance from Tome of Battle)
"While you are in this stance, you drain hit points from your allies. At the end of your turn, you can choose to deal 2 points of damage to each willing ally within 10 feet. For each ally who takes this damage, you heal 1 point of damage."


Crafting tricks:
- Transferring XP for creating magic items (http://archive.wizards.com/default.asp?x=dnd/we/20060526a)
- stacking untyped +2 "Aid Another" to achieve high Knowledge: Religion checks for Sacrifices to get Dark Craft XP points for crafting. (book of vile darkness)


Body Switching:
- (True) Mind Switch
- Magic Jar

Dunno if merging with your follower/victim as a symbiont does count? (If yes, have a look at the Curse Mark section in my Orochimaru build in the signature).
