Please don't rate the build before trying it ,i've tried many builds and this seems the best !

btw the calculater calculates things wrong u will have about 4100 mana only not 6300 and u will have 911 AP not 318 !!!!!!!! and that is because it doesn't consider the passive of archangeal staff that 3% of ur max mana is converted to AP so having 3 of them will give u 12% of about 4100 mana =492 AP + 155 from cape a+that of rhode of ages (80)=727 all this +30% of AP because of passive of rabandon's cap u will get 945 AP !!

Just don't think that this build is expensive if only you play the game right you will be able to buy all these stuff but you have to mid.

First buy mana regen Meki pendandt then keep lvling up till u get about 600 gold the go back to base get tear of the goddess and complete having mid then get archangeal staff and when u get turrets lvl 5 the game will start for u .

u will destroy ur enemy's turret using it and if he attacks u try always to place 2 turrets near each other and blind him then use ur powerful rockets.

i've added warthog armor because at ganking heimer. dies quickly so this will help him to survive and keep moving around ur placed turrets and u will dominate the game .

you will be the 1st one to reach lvl 18 which will make u OP than others
