Fully agreed with Zarna. A "sex doll lure" should just be one option. The initial "apparition" creator should have options for like lover, enemy, friend, family member. There's a whole bunch of character archetypes for whom "dream waifu" is jarring at best. Yet those same characters could succumb to the lure of power. Could lead to silly/ridiculous situations, like:

- Get off me, bitch!
* much later *
- Wait, that succubus-whatever was just a ploy to tempt me to the dark side and give me eldritch powers? But I wanted to go to the dark side and get eldritch powers!
