Bug description: Using Grimoire of Sacrifice to sacrifice the actual demon you retain the ability to use their Special Skill using Command Demon. It works with Succubus, Voidwalker and Felhunter while when sacrificing the Imp makes Command Demon disappear even from Spell Book
Proof:
https://imgur.com/l91qnWN - This just shows I'm idle, with no buffs.

https://imgur.com/GcEXiox https://imgur.com/5b2bmOu - This one shows the sacrificed Voidwalker's Special Skill which gives me 30% bonus health for a duration (and it works).

https://imgur.com/pckl8gP https://imgur.com/rhveTy1 https://imgur.com/KNij8PF - It just shows I've summoned the Imp and sacrificed it later to gain the buff bit the skill completely disappeared.

P.S.: I didn't try if it works with Infernal or Doomguard too. My question is if Command Demon is intended to retain the player ability to use sacrificed demon's special skills or not. It's a bug either way I guess.

That's italian language in the images so "Potere Demoniaco" is the buff given by Grimoire of Sacrifice, "Barricata d'Ombra" is the skill given by the Voidwalker after he's been sacrificed.
