Because schools of magic in UA are kinda fun on a conceptual level, I'll try to go through all of them picking out good, bad and ugly bits.
Amoromancy (Love-Based Magic), from "Postmodern Magick" p.56
Stats:
-You get minor charges for flirting with someone. You can't do this more than once per month with any single person. Seems simple, but there is a trap - the person you are flirting with must be romantically or intellectualy interested in you (possibly as a result of your flirting). Lust or physical desire doesn't generate a charge. This means that the MC has full control on your charging
-You get a significant charge for getting someone interested enough in you to go on a date. Once per three months per person. Romantic interest condition stands.
-You get a major charge when someone wants to marry you. Once you got a major charge, you can't get any charges ever from this person.
The charge structure is kinda meh. I dislike it because it leaves too much in the hands of the MC.
Taboo: falling in love, or getting charges from only one person for a month.
The taboo is very easy to avoid, and, what I dislike, impossible to stage to leave the enemy adept without charges.
Random magic: Amoromancy's random magic is all about emotion control and perception control.
The random magic domain is ok. It's easy to understand what is and what isn't valid, unlike some of the other magic schools (Dipsomancy, we'll get to you).
Blast: Amoromancy blast is interesting. On the fluff level, the target feels all the heartbreaks it ever felt at once.
Overcome with anger, shame, and repulsion, the victim experiences a mild heart attack. He must flee the Amoromancer’s presence, probably in tears, to avoid the stabbing pains in his heart that her proximity causes.
Oddly enough, this is actualy not bullshit. The target hit with Amoromancy blast must flee, or take -20 on all physical actions. This makes Amoromancy blast a rather powerful debuff. Amoromancy doesn't have a minor blast. It's significant blast deals damage of a minor blast (melee damage - sum of digits), except to the people who had feelings towards you (here we have firearms damage - the number itself).
Formula spells: Amoromancy formula spells are decent. They follow the specified magic domain, and manipulate senses and emotions. There is pseudo-invisibility, there is pleasure spell. There is also a spell that makes someone so depressed they try to kill themself. Major Effects include creation of true love, permanently changing how everyone reacts to someone, and other brainwashing fun.
It's important to remember, that magic in Unknown Armies doesn't have saves (unless MC allows you to make a skill, in which case he'll probably fuck you over when you try to do magic yourself).
Foot in Mouth
Cost: 2 significant charges
Effect: For the next half-hour everything the target of this spell says is taken in the worst possible light. The target’s exact words remain unchanged, but reprimands seem overly harsh and pointless, expressions of love sound false, and sincere professions of innocence seem like clever deceptions. Everyone who listens to the target feels the same way, but the target is unaware of the effects of the spell (except by observing the effects it has on others).
Overall, this is a decent school. The effects are clear, the charging is clear, the taboo is clear (if weak). I slightly dislike it for arbitrarium charge nature, but since most minor charge generation will happen off-screen, it's bearable.
