Salt-separating barrel
This barrel was created by Caligula as his season devoted to the covenant. The barrel is used in the following way: it is filled with sea water, it's lid closed. Then the barrel separates salt from sea water, and destroys the water itself, leaving only salt in the bottom.
| Effect | Arts | Level | Range | Duration | Target | Notes |
|---|---|---|---|---|---|---|
| Separate salt | MuAq | 2 | Touch | Mom | Ind | GL3: Make water pure |
| Destroy water | PeAq | 10 | Touch | Mom | Ind | GL5: Destroy a liquid |
| combined effect | Mu[Pe]Aq | 12 | Touch | Mom | Ind | (effects added together) |
Caligula's Muto[Perdo]Aquam -lab total is 22. The barrel is a container for the water inside, and container's form & effect bonus is +5 create or transform within. With Muto or Perdo Aquam - Verditius' runes inscribed on the barrel, Caligula can achieve a lab total of 30.
The barrel is to be created as a lesser enchanted device, so the maximum effective level is 15 with a lab total of 30. That leaves two points of room for uses, giving 6 uses per day. The barrel can now be created in one season.
A sidenote: when the salinity in sea water is 3,5% and the barrel holds 250 litres of water, one use produces (0,035 x 250 =) 8,75 litres of salt. It weighs 18,9 kgs, or 41,667 lbs. Six uses per day creates then 250,004 lbs salt. If one pound of sea salt costs ½ pennies, one day's worth of salt costs 125 pennies.
As a business, this yields 190 pounds, 2 shillings and 1 penny per year.
