if you want to dominate your line, riven and very good for this, does not need Mana its a good help. Very good to win the line.

Runes

Riven could be a great AD Tank i use armor penetration, armor and magic resist to tank the most as possible, and use armor penetration to get the most out of possible damage. you could use some physical damage too but i think armor penetration is better.

Masteries

In Masteries i use 21 9 0 or 21 0 9.
21-9-0 if u like the bonus armor and health (i use that one)
21-0-9 if i like extra movespeed and buff duration or if they have a level 2 jungler gank or a strong jungler in general

21 just for mass damage.

Itens

at level 1 i usualy cloth armor and 5 helth potions, then i buy wrigglre`s lantern to give some armor and atack damage, and also to save money on wards. and then i buy boots with armor to tank a litle bit. and then the big frozen Mallet to give helth and some Atack damage. Then trinity force to give some atack speed and some atack damage. and then i buy warmog and atma`s impaler/color] to tank a lot

Skill Sequence

At level 1 i use the Broken wings its good to take damage form your enimies and its good to rune away too. At level 2 i use the Ki Burst to stune the enimies and then at level 3 i use Valor to run away or to make a combo.
My combo: I use the ultimate to give more atack damage

I use Valor

to go to the enemy, and then i use Ki burst

to stune him and then the broken wings.

to try kill him

Summoner Spells
