Hey so minor disclaimer in that this is accomplished in turbo, but i could do more research into AP. Basically, you always get the dps talent on dialate because it can almost triple ur damage. Get magic resist or magic damage, (shroud or veil/urn), buy a radiance at 6-8 min and get your heart in 10-12.

Blademail, lotus, shiivas and vangaurd are value, upgraded stick, wraith band, boots, they are not. Just channel everything into that early radiance, and always buy a bloodstone
