By the time you can be doing this, Soul Contracts aren't worth 7 blood slaves per turn per turn.

You have level 9 spells, if you really cared about making Devils with blood magic, you'd make them with Infernal Forces, which comes with an army of imps and may very well be cast through Mount Chaining or even the Summoning Circle for a tremendous cost savings and the Devils come now instead of 7 turns from now which is a huge help.

No, if you want to make blood slaves with Forging, I suggest you make Dousing Rods. Each one increases the chance of your blood hunters successfully coming back with blood slaves, and it adds 1 to the number of blood slaves each comes back with. Those things are actually worth 2-3 slaves per turn.

Soul Contracts are great, but if you have the ability to Wish for unique magic items they aren't worth 7 slaves a turn - not even close.
