Re: Krobelus item/skill build
There are many item build that works.
Starting items would be basi, wand, bottle if you solo mid.
Against a heavy magic damage team a good build would be arcane, point booster, followed by hood, and then vital booster, and complete the soulstone by disassembling the arcane. Follow up items could be meka, sheep, shiva.
Against a dps line up, go arcane, meka, followed by soul stone, ghost staff, shivas, sheep.
Soul booster is extremely good since arcane is very good for her in the beginning, and in the mid game, you can turn 2300 into 450 hp (much better than vang which only gives 275 hp)
Skip the blood stone. If you have a soul booster, it is much better to use that void stone for sheep, and RoH for hood/pipe.
Situational item: Blademail, either gives you 4 for your ghost to hit your opponent, or your opponent eats 2k pure damage for killing you.
I have discovered recently that ghost is extremely imbalance for her if the enemy team is Skeleton King, Mortred, Sniper, Clinkz, Viper. Ghost + TP (and maybe a silence to stop the stormbolt) means you are unkillable, and that 3.5 sec could allow you to just destroy towers, heroes ect.
