prospecters- rlylais,abyss, witchcap, voidstaff, bft
the building order really changes every game, if im getting ahead early i grab voidstaff asap then go into abyss or BFT depending on how fast i can make money.
when im having a harder time i will get defence of the person(armor/ mr) then i will get hunters guise,voidstaff,rylais, then either finish the bft or the armor/mr item i started building earlier in the game.
i am far from high elo but have a much better then 1 w/l record on diana. i would love to hear some diana input from someone high elo if they had the chance tho.
