Drop rate on dungeon rare (blue) heroes - Executioner particulary ?
Been trying to fuse a epic (purple) hero Relickeeper , and hunting Executioner in Hollowed halls (6 energy per run) for hours in row now - 900 energy spent 3 toons from level 10 to 40 raised , and 0 drop.
Justicar (one of requisites) took only 120 farm-runs to get (4 energy per run).
Is there data-mined drop rates anywhere out there ?
Seems like gamble-game with highest out there p2w prices. And those everytime poppingf alerts ...
