Not Updated For Current Season
This is my first build! so please enjoy! Will add more text to this when i get more ideas/criticism.
About the items i recommend that you start with Sapphire Crystal and 1 health and 1 mana potion.
Come back when you have money to buy tear of goddes and sorceres shoes than buy another tear of goddes. after that make 2 archangels from the tears of goddes. Than make 2 more archangels and 1 rabadon. if you get this far sell your boots and buy fifth archangel. with these items you should be able to 1 hit enemies easily if they have hp under 3000 and little AP.
REMEMBER!: With Archangelss you must use abilities to gain max mana so you can get like over 1000 AP.
Most people would start with the doran's ring but i think its unnecessary if you will go to mid and know how to last hit creeps.
