It's just so many things wrong about this guide. First of all, all games are not the same. I'm talking about the armor/magic resist that you have put together. Your marks, glyphs and seals are just wrong. HP/lvl, magicresist/lvl and dodge are worth gold at any tank. It's in the end of the game that everything goes down so wouldn't it be better to go for better late game tank? And since you have 0% dodge the mastery Nimbleness becomes a wasted point, so is the 3 Ardor points in this case. You have 0AP and you don't need attack speed at all, because you're a tank. Would be much better use at Harden skin and possibly Defensive mastery. And maxing Bandage Toss before Despair is something I don't like either, once again, you are a tank and you do so much more damage if you max Tantrum first, have 1 point in Bandage Toss and then max Despair followed with Bandage Toss last. Bandage Toss just becomes more mana expensive with every level. Amumu doesn't have that much mana until midgame and trying to chase someone with no mana is not recommended. Last thing that I think is wrong with this guide is the wasted summoner spell for Clarity. Amumu doesn't need it at all, just control your mana usage. If you want to last hit creeps with Tantrum, just get Philosopher's Stone. Isn't expensive at all and it gives you back the gold when you are done using it. The game winning thing with Amumu is his ultimate, so you should use your summoner spells to position it as good as possible. Ghost / Flash is best for this Little Emo Mummy.

If you haven't noticed, Amumu is my main tank, would probably even say main hero. I know what I'm talking about here. Voting negative
