The game markets itself as D&D simulator. It even manages to play like one which is rare until Act 3 happens. The core of CRPG genre is givin the player the freedom of action, however unlike IRL Dungeon Master the game can't possibly adapt to every player's possible action (some DM can't adapt either). But it skill kinda can by the virture of aknowledgement. You either let me to the thing, or explain me deliberately why I cant. And they could explain it very easy if they tried: 1) Ressurection after detonation? Sorry bud, infernal engines are blended with a soul and destroy it upon detonation! Pretty logical demonic crap! 2) Ressurection before detonation? Eh, the engine detonates upon victim's death, out of options! 3) WISH spell? You know nobody who can cast it, your level cap is 12. Elminster could help, but he either lost access to it or is saving it for some terrible doomsday event. 4) Elemental planes? Sorry bud, forget high temperature bullshit, this NEEDS to be Avernus for engine to function properly! 5) Divine intervention? Well gods can just straight up refuse, but at least we tried eh? 6) Steel watch? Sorry but her engine is really old and defective and will detonate upon further attempts of modification/removal. Boom. Spread this info over 3-4 dialogues and her fate shall make some sense. I, however, still refuse to play a lighthearted D&D campaign with talking animals and silly jokes where the DM deliberately strips me of power to save a very likeble character because apparently fun is not allowed. Not my cup of tea.
Tbh when I saw her first, how she acted and her quests in Act 1, i hyped myself into believing that her questline is pretty much Pimp My Infernal Barbarian episode where in the endgame she becomes unstoppable demonic justice dispencing machine with a biggest and most hard-hitting metal stick that could be found in-game. That got my gears goin until I learned of her inevitable demise.
