i like Dawnguard but i do not like the fact how there is a bug in this dlc,
the Drain Vitality shout is fun to use when it is not buged, but this shout has a bug
to come with it. so when i first playing this game, i was mad to the fact that it had a bug to go with it but now i found a way to to fix those two Drain Vitality Bug that shows up of 1 & 2
so this text Note pad helps you fix these bugs.

so you can play skyrim free and have only one true Drain Vitality shout
no buged ones :)

do not use the mod manager, just downlaod this file normal
thats all.
