I need help!! My death knight is at lvl 7, and knows one handed-melee slash skills. Lets say, I walk up to a merchant that is willing to sell me a one handed melee skill slash specialty. What would happen if I purchased a skill that I already have? I know this is confusing, I'm sorry. I purchased the skill thinking that it would give me some type of statistical boost, but the only thing that I noticed is that I was short of 4000 gold.
Any ideas? Thanks!
