Alright... I want to compare my design for this with what people see as necessary. It's right after my game, so I'll post my details and number breakdown until tomorrow.
In short: A golden tap, which when inserted into a barrel of liquid, even liquid as simple as water, will transform the liquid that passes through it into fine alcohol. There are 8 types of alcohol that can be produced: 2 beers, 2 wines, 2 ciders, and 2 meads (I think I'm remembering this right).
These types of drink are preset, and their temperatures are also preset (Ignem prerequisite) so that one variety of cider might be hot, for example.
This sounds like natural liquid to natural liquid, and the individual target effecting a large barrels worth of base liquid seems to work.
The duration is Sun, so +2 magnitudes.
I threw in a magnitude for the variety of liquids.
He also wanted the drink to change an unlimited number of times, so people could choose a different one of the eight drinks every time they filled a cup. +10 levels.
So, it'll be a golden tap.
Bleh, tired. Will post his stats tomorrow...
