Re: Chaos Knight Build
Good CK build? Depends on your play style. What CK needs: Strength - for HP and damage, a bit of mana early game (around +200), lots of IAS starting mid game in the game, and maybe an orb late game.
Now about the roles:
Ganker? Treads or Phase, Bottle, Bracers, Armlet or Diffusal. Reasons: Treads for Str and IAS, Bottle for regen while you're running around, Bracers for Str and a bit of Int, which you badly need, Armlet for quick damage or Diffusal for bonus damage and an extra snare.
Carry? Hard to play, since you need lots of farm. Treads, Bracers, Manta, Heart, whatever you want. You carry by taking down buildings with your images.
