Ok, ive had 2 shouts for "Drain Vitality" now for some time.. One leeches 1 hp, stam, and magicka, the other leeches 2 points for hp, stam, and magicka... Doing the dawnguard quests (which ive just started), i just aquired my THIRD version of drain vitality... Whats the deal?

The 1st two have the 3 same exact words, but do different amounts of leaching.. Mmk, its ps3, maybe yet ANOTHER bug.. But thia new one, the 1st word is "Stamina", and the effect reads "Coax both magical, and mortal energies from your hapless opponent"...

Can anyone clarify for me whats going on? I have 1 word for the Dawnguard versiopn, and all 3 for the origional 2 shouts... The wiki pages have discussions, but they seemto mix in another shout "Marked for Death" in the discussion, and it becomes too confusing to follow...

It's bugged. I only have 1 copy. Try getting all the words for "Marked for Death".

The version of Drain Vitality that dragons use was set to have the Words of Marked for Death, which causes issues with learning words for Marked for Death -- you may learn the supposed-to-be-unobtainable dragon version of Drain Vitality instead or as well.

This has been fixed by the Unofficial Dawnguard Patch for a while, and the fix is retroactive, too, if you have an existing game. If you're on a console or refuse to use the patch, well, then, you're up crap creek without a paddle.

You can find the real shout in your list, it will be the one that has no dragon souls activating it yet.

The bugged dragon shouts that you obtain through the marked for death word walls are already activated.

I would not use them. I do not know what happens if you do, but in a game as complex as a TES game it is always a good idea not to randomly go playing with accidentally uncovered mechanics your character should have no access to.

I have all 3 words for both drain vitalities with the same words in them.. One leeching 1 point, the other shout leachign 2 points... Today, i got another one, but the 1st word (the only one i have for this one) is different.. It was obtained from a dawnguard quest, when (SPOILER)(SPOILER)(SPOILER)(SPOILER)(SPOILER)(SPOILER)(SPOILER) when rescuing the Vampire daughter withthe elder scroll on her back... This one has different effects, and different words than the two i already had... But the origional two, i have all 3 words for both... I cant recall if i have all 3, or only 2 words for Marked for Death however.. I was just about done with all the vanilla shouts, minus the final word in 2 or 3 shouts...Maybe marked for death isnt complete, and ill check back in when i get off of work, and complete it..

Yes im on ps3, and always update when ones available.. Also, have ps+ which does some automatically

Erm, not sure if you understood: the Unofficial Dawnguard Patch is a modder-created and run patch for Dawnguard; it's a mod, in other words, though a frequently-updated and professional mod, with a bug tracker where the community can submit bugs for review and perhaps inclusion, and where folks can add files which fix bugs to be included within the patch.

Since it's user-created content, it's only available for PC. Bethesda doesn't usually patch expansions, though they have on occasion placed bug fixes for DLC in their updates.

It is unlikely that this error will ever be patched; the "correct" shout should drain only stamina if you have one Word only, and I'm not certain if these bugged shouts will preclude your ever learning Marked for Death.
