Not Updated For Current Season
Manamune after boots. its not in the item list yet so i couldnt put it down. but basicly, "+350 Mana +7 Mana Regen per 5 seconds +20 Attack Damage Passive: 2% of your maximum mana is converted to attack damage. Passive: Whenever your champion attacks, they gain 1 max mana (2 second cooldown.) Whenever your champion uses an ability, they gain 4 max mana (3 second cooldown.) Bonus mana caps at 1000." I have tried this build a few times and it always dose very well. Manamune solves mana regen and overall mana issues. it also gives a very noticeable boost in damage even when you first get it. importanat to build Tear of the goddess as soon as possible though, so youll have a better attack boost when you complete Manamune.
Brutalizer for cool downs mostly, cant say the damage and armor pen dont help though. haha. But the cooldowns thing is a must, too many times when your gonna be counting down the seconds for a heal or pretty much any of your other abilities. so if you would rather go for something that gives you some other necessary stat other than attack damage, based on who your opponents are, then this is the item to do it with.
BF sword or Pickaxe to start off Infinity Edge. get the cloak of agility last when building it.
Zeal first when building phantom dancer cuz of the speed boost.
I honestly never get past Phanton Dancer, But if you have an urge to build Youmuu's, be my guest. haha.
Constructive criticism is appreciated. =)
