Physical Representations (Physreps)
If you acquire any potions, scrolls, poisons, or alchemical substances during your adventures, they will have a tag attached. If you create your own through the Production Points system, then you must supply a physical representation (“physrep”) for the item, and the tag must be attached. This physical representation can be stolen, at which point the thief will take both the tag and the item.
A tag by itself is not a valid item. You cannot utilize a tag without a physrep to take an in-game action (like drinking a potion). This rule exists because in-game these objects should take up room and add weight. You can’t carry around a hundred potions as easily as you could a hundred tags.
Keep in mind that the tags themselves are stealable even without a physrep; you do not become immune to thievery by ignoring the physrep requirements. If you have a batch of tags that you have not attached to physreps and someone searches you, you must turn them over. Similarly, these tags can be destroyed by applicable Traps and similar effects even though they are not attached to a physrep.
You must provide your own physrep for magical weapons and items you create in-game, although there may be times that one will be provided in-game. Once the physrep is in-game, you cannot alter the weapon in any way except to repair it when needed. If the physrep wears out, then its replacement must look as close as possible to the original. Contact your local Marshals for guidance if you are unsure.
If you have a personal physrep that gets enchanted (for example, a suit of armor) and the item is stolen in-game, you have the right to refuse to turn over your personal physrep. You must still, however, turn over the tags for that item. In exchange for keeping your own item, you forfeit your right to “recognize” your special armor later when the thief wears it in-game (using your tags with his or her own physical representation).
