According to my experience so far and as the Leaderboard says we have a “Siphon Blood” domination on the list;
*Trag’Oul Death Nova - Siphon Blood
*No Six Piece Set - Siphon Blood
*Rathma - Army of the Dead Build with Siphon Blood
*Grace of Inarius - Siphon Blood
*Bone Spear Masquerade
*Pestilence Corpse Lance
and before finding the all build items “LoD Corpse Explosion” build works well,
any other builds did you try?
