* This code adds a new spell, called alchemy. Alchemy will turn |
1555 |
* objects to gold nuggets, the value of the gold nuggets being |
1556 |
* about 90% of that of the item itself. It uses the value of the |
1557 |
* object before charisma adjustments, because the nuggets themselves |
1558 |
* will be will be adjusted by charisma when sold. |
1559 |
* |
1560 |
* Large nuggets are worth 25 gp each (base). You will always get |
1561 |
* the maximum number of large nuggets you could get. |
1562 |
* Small nuggets are worth 1 gp each (base). You will get from 0 |
1563 |
* to the max amount of small nuggets as you could get. |
1564 |
* |
1565 |
* For example, if an item is worth 110 gold, you will get |
1566 |
* 4 large nuggets, and from 0-10 small nuggets. |
1567 |
* |
1568 |
* There is also a chance (1:30) that you will get nothing at all |
1569 |
* for the object. There is also a maximum weight that will be |
1570 |
* alchemied. |
