the idea of this build is not a glass cannon so don't get the wrong idea. Vi has plenty of power naturally so most build her hp def but that doesn't sit well with me. Early game build is based on keep a slight hp regen but for farming gold fast ravenous hydra is a great way to do dmg regain hp and gold fast. the extra dmg boost from activating it has killed many champs for me essentially its my ignite. but also i have the black cleaver oh yes vi is insane with armor shredding at the start add a blk cleaver with the stacking armor shredding and its a party already.but if that wasn't enough mid game u build infinity edge the extra 70 dmg plus the critical boost of 250% when u crit its heaven. ive been in many games where champ have been fed so they get cocky and my infinity edge starts to drain hp to 1/4 1/2 3/4 and they get scared fast. but all champs are weak to stuns but vi is the worst in my opinion she rely's on heavy hits and cc. so late game is when u build her tank side ur going to want warmogs armor tht extra 1k hp is a blessing plus the 1% hp regen. also sunfire cape her cc keeps ppl in place so armor, hp ,and fire dmg are all an asset when ur stunned ur still doing dmg even tho ur locked down. last but not least to be a lil troll when ur locked by stun , blind, or slow use thorn mail because ppl wont think bout how much 30% of a basic attack is with all ur hp def and extra aoe dmg plus dmg being dealt back to them ur a force to be reckoned with. id say ud more than likely win that scrape and if you dont uve weakened them for ur team. and yes i know i use to many txt short cuts idc my grammar is bad i still don't care im not here to please u so shove it the rest of the world doesn't care and i realize i should be capitalized i just don't do it.
