yep, i think its really effective... especially on Luna, vengeful, broodmother, or even gondar and lots of other heroes.. ARCANE RING.. i tried it on luna, her 1st skill got long range and fast cool down that i can spam on.. (even my opponent got vanguard or defiance, he still goes home or dies!) i tried it on venge, same thing happened, my opponent cried, i even use my stun on last hitting creeps. on brood, i tried using arcane and try last hitting creeps on her 1st skill.. INSTANT PUSH!! arcane + meka + vlad + treads = gg!, i even experienced 15 mins, his tree got destroyed... NOTE: later on, when u have farmed and lvl gapped ur opponent enough, sell ur arcane for extra slots.. WHAT DO YOU THINK? BTW, try it... btw, midas and arcane as 1st item is effective too.. depends on ur opponent if u must put vanguard in exchange for midas..
