hi! A player picked up this skin in my campaign (well, 2 sessions so far), and it seems to work fine, although it really needs to specify what happens if you bestow a gift to an NPC. The easy way could be to put them at an advantage, but maybe something different can be done, because the advantage is to NPCs the equivalent to a +1, and this is even better. Perhaps coming out of nowhere with a hard-hard move? (damage, strings, conditions, etc.)
Also, I think there are too many moves, in comparison with other skins. I'd perhaps cut out "the dark powers are always willing to help", "just this time" (too specific, and only against PCs), and also cut out any one of "my bitch" and "the devil is a winner". Finally, addictive could perfectly be part of the sex move: "they lose all strings over you. If they have none, they gain instead the condition 'addicted to [your name]".
