...innnnteresting. Either Milani doesn't know what has Asmodeus's squirrels so excited - or She was willing to sacrifice all of the benefits She hoped to gain, by that tactic, to make it look as if She's ignorant.
36 new souls for one torment stayed is still far too low, of course, especially if Asmodeus isn't allowed to know the purpose. Try 3600! Though Asmodeus might consider a lower rate, if Milani were willing to accept this rider stating that no such unseen exercise of a stay of torment will be used in a way net harmful to Asmodeus's other interests; such as, for example, by using it to suborn one of Asmodeus's trusted subordinates and remove their fear of Him. Milani talked a good game about how all this would be a nice Abadarian trade in the overlap of their interests; was She, perhaps, less than fully sincere in Her intents?
(What is She playing at, here...)
