All Quiet in Music City
Mana potions, energy drinks, hormone-induced rage . . . all of these concepts found in other games and genres can be types of Tass. Essentially it is a distilled, physical form of quintessence that can be stored on one’s person and traded from one supernatural creature to another. It functions exactly the same way as quintessence stored in one’s avatar or found at a node.
One must first be adept with Prime magic in order to create Tass, since the mage is effectively channeling (i.e. enchanting) an amount of quintessence into a physical object of some sort. There is no “real” limit to the amount of quintessence that can exist in a single object of Tass, but all mages are advised not to store too much, lest they tempt Paradox or other powers that be.
