Abaddon is a hero that fits many roles, both carry and support. This is my build for a hard carrying, NOT support, Abaddon. This build is best played in top lane (Dire) or bottom lane (Radiant), the safe lanes, and EVENTUALLY jungle. If you secure good farm for Morbid Mask and Hand of Midas early game, you're set in jungle. The trick is picking another ranged hero that harasses in lane with you until you jungle, thus giving them a solo lane when you are finished. Once you have Skull Basher, go solo Roshan.
