* This code adds a new spell, called alchemy. Alchemy will turn |
1376 |
* objects to gold nuggets, the value of the gold nuggets being |
1377 |
* about 90% of that of the item itself. It uses the value of the |
1378 |
* object before charisma adjustments, because the nuggets themselves |
1379 |
* will be will be adjusted by charisma when sold. |
1380 |
* |
1381 |
* Large nuggets are worth 25 gp each (base). You will always get |
1382 |
* the maximum number of large nuggets you could get. |
1383 |
* Small nuggets are worth 1 gp each (base). You will get from 0 |
1384 |
* to the max amount of small nuggets as you could get. |
1385 |
* |
1386 |
* For example, if an item is worth 110 gold, you will get |
1387 |
* 4 large nuggets, and from 0-10 small nuggets. |
1388 |
* |
1389 |
* There is also a chance (1:30) that you will get nothing at all |
1390 |
* for the object. There is also a maximum weight that will be |
1391 |
* alchemied. |
