Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
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.
