Astromanium Yeah so this build was abusing a bug which allowed the Zombies to cast Sacrifice while at negative mana. This build should still technically work within 1.0 but cripples the Sacrifice aspect of it. I will need to test it but with the current server states, it will be a while. Currently I would recommend just running the Zombies variant of this and building around them and not Sacrifice as that does not require mana to use just potions.
The only way to get the same damage output would be to get a an equal amount of mana back while sacrificing. I don't think is possible.
