XIII. Mercatus (Trading): Commutatio and Emptio
- Types of Mercatus. There are two (2) types of mercatus:
- Commutatio: bartering between players;
- Emptio: buying legiones/classes.
- Commutatio (Bartering): Foreign numina (Tyr, Wotan, Isis, Mithras, Tanit, Ishtar, Cybele, Ares) oversee commutationes and may witness or formalize the exchange
- The terms of commutationes are up to the individual players;
- Items which may be bartered:
- Players may freely trade legiones clientarum and classes at any time;
- Players, however, may not trade or sell legiones curiales or suffragia;
- All players engaged in commutationes must be present in the same region.
- Emptio Legionum (Purchasing Legions): Designated numina oversee emptio legionum, as follows:
- Legiones curiales. Only certain Olympian gods may sell legiones curiales (Juppiter, Juno, Minerva, Apollo, Diana, Vesta, Vulcan) at the designated cost (200,000 D);
- Legiones clientarum. Only certain foreign numina may sell legiones clientarum (Tyr, Wotan, Isis, Mithras, Tanit, Ares, Dionysus, Ariadne, Silenus, Monut, Ishtar) at the designated cost (400,000 D).
- Emptio Classium (Purchasing Fleets): Sea-gods (Neptune/Amphitrite/Oceanus) sell classes; classes may not be bartered, bought or sold in Parthia or Germania.
- The Nature of Emptio.
- Any numen in possession of any saleable property must sell it to any mortal player who has sufficient funds and is permitted to buy that property;
- Numina may not purchase properties from other numina, including the Fates; the only way for numina to come into possession of legiones is to win them during a proelium (VII.D.3), capture them at sea (VI.E), or confiscate them (II.A.4.a);
- Players may purchase saleable properties at any time except during a proelium, i.e. from the issuing of a flagitatio until the proelium is concluded (VII.C)
- Players may determine the availability of properties by any means of communication (X).
- Juventas. Juventas restores youth and vigor to chosen mortals. She may give mortals properties or Denarii which she has requested and procured from numina.
