Nice, will have to keep an eye on that next time I'm playing a tank-y champion.

Usually Atma's Impaler is a noob trap. It only grants 15 AD per 1000 health. That's 45 ad if you have 3000 health which is about the average amount for a tank.

On a tanky champion, you're almost always better off building CDR if you need more damage, so you can use your spells more often. The base damage and the crowd control on your spells make it more worthwhile to maximize spell use over attack damage. CDR comes bundled with more health in Kindlegem and its upgrades or with armor in Frozen Heart, giving you the added benefit of being even more tanky while you disrupt the enemy team.

I only use atma's on riven... frozen mallet, warmogs, and atma's. Blood thirster and black cleaver are nice on her too

Actually, I shied away from atma's my last few games. Doesn't seem that worth it.

meh for some characters it isnt

Well it gives crit as well, and it's component gives extra gold on farming as well as gp 10

lol cooldown reduction riven is so stupid

CDR is great on Riven you don't main the CDR but you get some through things like ghostblade. Lets you spam your moves more. A lot of tops get really strong from CDR rather than making their attacks actually stronger they bring them out for CC and such more often instead.

A big difference between atma's and other items is it helps top significantly. They are generally more tanky and it gives 45 armor. It gives 15% crit, and at 3000 hp it's a bf sword equivalent. It costs 1650 assuming you have the beginning parts which is only 100 more than bf sword, but it also gives all the other stats along with it. All in all it's a good cost effective item.

lol yep... when i play riven i try to rush for a blood thrister

Which is a good item for her, and people use to get ghostblade for the CDR and buffs because she is not really a basic attack champion. The changes to Black Cleaver though have replaced the ghostblade. A normal build for her in order would be. Merc treads, Bloodthirster then 4 other items in sequence depending on the time. (Guardian Angel, Black Cleaver, Randuins, and Maw of Malmortius) Maw comes sooner vs AP tops. It's a very solid build for her, and gives some CDR not a lot but enough.

yep that sounds right... i like merc, blood, black cleaver, frozen, guardien and maw

Yeah frozen is a good interchangeable option for frozen, but one helps chase one helps team fights. Riven really has no reason to build anything but ad since her shield is AD based.

yep pretty much... OH i love they hydra on her

Again wouldn't say she's much of a basic attacker so I avoid things like that.

meh... i like the active on it

Yeah it does have a nice active. It's pretty much another skill for you to use in fights.
