Of course, real coffee is hard to come by, and Path of the Espresso is not magic for street kids. You must take a geas : drink real coffee (Espresso) every morning, and if you use milk, must be real milk.
This tradition has a mentor spirit of finely made espresso, having this mentor gives you bonus to initiative, don`t know how much stat wise... don`t want to overdo it.
And penalties if you don`t drink your espresso.
First, i think its pretty logical what spirits are used :
Fire - you need heat to make water boil.
Water - Did i said "water boil"?
Plant - Its obvious, it grows on plant.
Beast: some people put milk in their coffee. And milk comes from cows
and finally Man, as man or woman makes coffee and drinks it.
Drain value are logic + willpower, as coffee is seen a drug of smart and educated masses,
I am also tempted to make it charisma and willpower, as after coffee consumption i feel more talkative and less able to think.
Now which spirit does what, that was a hard part:
I think milk is healthly, and as beasts are related with milk, we have Beast spirits for healing stuff. A Esppresomancer summons a cow that heals you. That was the easiest.
Water: Combat. The espressomancer hits you with hot water, your brain is cooked.
Fire: Illussion. Now it does not make much sense, but look at these pretty little flames, while the esspressomancers group is stealing your stuff.
Plant: Detection. Lets say the coffee plant start to grow at places where mage can't get and gives him second sight.
Man: Manipulation. Its him of her who manipulates all the other elements, so he or she get the manipulation domain.
Voila, instant magic tradition. On no circumstances you could use instant coffee, thats ew
