Well dang, would've saved me the effort if I saw that earlier. Oh well. Truly love messing with Silence, or as I like to call it 'Cut Content Enabler'. Incredible in-game utility tool, provides access to so much content either cut or intentionally made inaccessible (like bringing Minthara/Halsin into ACT I and the Creche).
Exploring the game's once existing potential is quite exciting, yet also depressing when seeing how much of the elaborate story is buried underneath and forever out of reach due to rushed development - as evil choices weren't just lazily cutting off content as they do today, but had actual branching story with satisfyingly lasting outcomes.
Thus the whole reason why the effort was made in the first place to try and avoid the intended lazy outcome, didn't want this power-hungry playthrough to be completely devoid of content in ACT III yet again, so thanks to this little spell got Shadowheart as a Dark Justiciar and myself as the Slayer, along with Isobel and everyone at Last Light Inn alive and well - all for the price of a single celestial daughter.
If the game won't provide satisfying evil outcomes then I'll raise the satisfying outcomes from the dead instead! (Balthazar would be so proud)
