The World of Althéa has a long history and has undergone a number of cataclysmic changes during its time. Part of this adventure will be to learn how the world has changed yet again, and how this change has had an impact on its people and your own characters. As such, your PC’s learning curve will reflect your own when it comes to certain aspects of the game. However, there is some world knowledge that can be shared now as it differs from standard NWN games you will have played before. This is not exactly game "mechanics", which is explained in the next section of the manual, but a continuation of describing the "flavour" of Althéa.
As Althéa is considered a "low magik" world, there is little need for the huge amounts of gold that are often used in other game worlds. A high gold economy problem arises because each "better" magik item that enters the market forces a higher price to be needed for its acquisition, which quickly becomes ridiculously high, skewing many other price factors and forcing builders to "fudge" other costs. While fudging costs this way may fix some results, it often leaves many other items greatly out of proportion. E.g. Often, the costs of components to create an item are considerably higher than it would be to buy the product already made. Such an economy only serves to devalue any crafting skills a PC may have.
To this end, many of the game’s 2da files relating to the costs of items have been recalculated and reworked to reflect an economy geared around the cost to cast spells at a given level, and then all other cost factors were arranged around these figures. (See the table below for the calculated costs of each spell.)
As a result, many of the more expensive items plummeted in cost, to around a tenth of their original value. This, however, fitted more closely with Althéa’s economy where 1 gold piece (gp) was an average day’s wage; meaning it would not be unreasonable for an average NPC to be able to afford the cheapest potions after saving for a short time.
Further consequences of this lower priced economy means the cost to craft or enchant items has greatly reduced, but continues to reflect a more realistic scale of costs where the items can be found in the first place. More importantly, PCs who can craft will now economically gain from doing so.
