False Coin

This is a spell which if not used with care, can cause serious damage to the economy. Casting False Coin on a pile of coins, regardless of which currency, creates five more stacks of said currency of the same worth. While it is said these coins are only temporary, they indeed are permanent, exact duplicates.

It is unknown what made the mages of Moonshade to create this spell, and also why it hasn't been used to cause serious inflation, as it is very easy to cast and cheap, compared to the possible gain.

Trivia

 * In hindsight, that the guards at the Bull Tower explicitly want a Gold Bar from the Avatar actually does make sense. They probably know of this spell and are satisfied with a gold bar, as gold bars can't be replicated with it and thus retain their value.
 * Due to the fact that all money exchangers die later in the game, some of the still usable currencies and the ability of this spell are needed to replicate enough for the few buying opportunities left.
 * For Monetari that's Wilfred and his training.
 * For Guilders that Mortegro and his spells.
 * And Gold Coins for training in the past of The Silver Seed.
