Still, Scarblade was a trooper and went through the whole ridiculous attunement process. He says he tried both Frost and Blood specs before ultimately settling on an Unholy build that won the day for him. Personally, I expected this kill to have been done using a deep Blood talent spec with how well they solo. I suppose Onyxia isn't the same as your random elite thug hanging out in the middle of a field somewhere, so it makes sense that what works there might not be best in Ony's Lair. Unholy does make sense though, controlling those whelps can make or break an Onyxia attempt no matter how many people you take with you. Unholy Blight is a beautiful thing.
Yes, Scarblade did earn an Achievement for killing the ol' gal. Two, actually. One for just plain killing her, and one for killing her solo.
