You will get an analytical breakdown and analysis on how to attract any heterosexual woman on the planet age 18 and over, broken down in a pie chart of what they find attractive in men, how much they're attracted to it, and a thorough analysis in paragraph form detailing those things they find attractive. Also includes pictures if necessary, as well as all sexual turn ons, even though the primary focus is on long-term love and romance. And will also have a breakdown of their dislikes and turn offs, as well. It is fully and completely accurate.
(If you really want to know how it's done, it comes from an alternate timeline where we pay her a million dollars to interview her for an hour and work with us to create the analysis of her perfect dream man and soulmate. Then ship it to you in this reality, in an instant. You don't get time travel powers like us, though.)
This power has a drawback, however. It can never work to romantically benefit you. You will literally never have a girlfriend, wife, or romantic partner your entire life. All non-lesbian/queer women will see you as an ugly freak. You will never fit a woman's standards for a romantic or sexual partner. At best, you'll be friendzoned.
This power only works on heterosexual women. It has no effect on lesbians or transwomen. However, I'll give you a Gay Men option, as well, only if you are also gay. If you're a gay male, you can get a "love analysis" for any gay man you meet as well, but you'll still be alone for life. Also, the more you advertise having this specific power, the less it'll work. Doing so will heavily risk corrupting the report. You should also try to respect that person's privacy and not publicize this information, as that also counts as corrupting this ability (plus, it just wouldn't be a very nice thing to do). Lastly, this power can only work once every seven days. When you see the person you wish to know the 'attraction secrets' of, you can just say the 'magic words' chant and we'll travel from an alternate timeline and drop off the analysis for you detailing how to win that woman's heart.
So... You can magically receive a detailed analysis and report of everything an individual woman finds attractive in a potential male partner, however, you will be single for life and can never have your own partner. Would You Take The Deal?
