* value (magic) of the armour can never be increased beyond |
479 |
* the level of the character / 10 -- rounding upish, nor may |
480 |
* the armour value of the piece of equipment exceed either |
481 |
* the users level or 90) |
482 |
* Modified by MSW for partial resistance. Only support |
483 |
* changing of physical area right now. |
