Demonology

The existing demonology calculators didn't quite work for me. So, I created my own: Demonology Calculator It calculates the required number of sacrifices, the required number of pets (spawn), and the total HP of the sacrifices. You can enter numbers or simply use the mouse/up/down buttons to adjust the exact number of units per sacrifice, taking into account the available pets (which are always insufficient at the beginning). Any excess can be saved for later or used for single units.
