this build is plain and simple and will dominate any1 in 1v1 and even in 2v1 u can always buy bf sword first if u have the money for it but pickaxe is usually the easier buy for earlygame jungling, with bf sword of pickaxe u can start farming in the jungle on all mobs except dragon, usually u'll be around lvl 7 when u get it and that is the recommended lvl by me for jungling all mobs (except the dragon!!!) u can do dragon at about 10-12+ depending on if u know how to actually play riven. Also the last spot can always be filled with another Infinity Edge or a defense item if ur goind up against high damage persons like tryndamere, jax, veigar, lux and morg (mainly if fed) thoose champs deal high magic damage so a force of nature would be a good buy and if a high damage ad is ur target then u might wanna get a thornmail, have fun, hope it works for you like it does for me, peace!
