Justification: Doppelwalk is normally gotten at level 1 because you rarely need a nuke at level 1--you then max out spirit lance for better early game power. DO NOT GET PHANTOM EDGE AT LEVEL 6. Some people say "phantom edge must be gotten at level 6 because it provides magic-resistance." Yes, it does provide magic resistance, but that's kind of useless at this very early stage of the game and given the bad hp you have. If you want survivability, get stats instead.
