Sacrifice shouldn't work on black dragons. Besides this "AoE" Geyser bug, the only things that did as far as I remember
a) Plague. level 1 plague was so efficient, I had to get it even as a warrior.
b) Rune Mage Crossworlds resurrection
c) Gizmo (Crossworlds later patch? Or was it red sands?) could heal black dragons
d) Dancing Axes of Shamans could heal black dragons
It is possible Geyser is allowed to hit black dragons now because a NEW rule in this game is
Giant's Earthquake can hit flying creatures now, but with reduced effect (only 30% effective I think). I personally don't like this, but eh.
By the way, Black Dragons initiative isn't THAT good (init 6). But they make level 1-4 enemies have -1 initiative (Power of the Dragon unit passive), so that is what makes them really good as "Interdictors" in battle, even if they aren't THAT great in straight combat against real enemies.
It also meant that the mortal enemy of the Black Dragon was the Archdemon (init EIGHT), who was faster AND was immune to the negative initiative.
But as a Warrior, I would have Onslaught and Quick Draw, one cast of helplessness on Archdemon (they can only debuff at the start of their turn, like Shield of Rage right now) and 1 or 2 shots of my 100% critical chance hunters, and the stack would be nearly dead. Who said damage doesn't matter?
