 If you google what spec to level with in Classic, most guys will just tell you to go Shadow. But I'm going to let you in on a secret, there's actually a better spec and it goes all the way up to level 40. The reason for this is because the early talents in Shadow actually aren't very good at all when it comes to leveling. You have a couple of good guys at the start and then everything kind of starts falling off. Mindflay isn't very good until you get more talents and higher ranks. And there's loads of useless stuff in here like Improved Fade, Shadow Affinity, Improved Mind Blast which is probably one of the worst talents in the game considering you don't mind blast on cooldown anyway. In addition we've got things like Shadow Focus which is going to overcap your hit if you take all of the points in it. Today I'm just going to show you a 25 version of the spec. So your ideal spec path for SOD is just going to be 5 out of 5 ones, 5 out of 5 Spirit Tap, 3 in Imp Shield, 2 in Martyrdom and 1 in Inner Focus.
