"Greetings. The Building Charts have been updated to reflect the need to use them to build, rather than convert, items. Hopefully they're a bit easier, and there have been a few additions (more examples for weight, new spells added to the tables, etc.)" -Mouseglove

Step I: Determine the object's Craftsmanship (CR) level.
Step II: Determine the object's Armor Class (if applicable).
Step III: Determine the object's Minlevel.
Step IV: Determine the object's Structure Point Rating (SPR).
Step V: Determine the object's Weight.

There are a few new ground rules you need to be aware of before we get to the charts themselves:

• No objects other than weapons or items worn on the head, hands, feet or held slot (sheilds only) may have +'s to damage, and only weapons may have higher than +1.
  
  
• Multi-slot items may have total +'s to damage as appropriate. (Ex. A buckler shield that also takes up the hand slot may have +2 damroll as it is a two-slot item. However, an object that takes up shield, hands and wrists may only have a +2 damroll, since wrist is not an acceptable slot for +'s to damage.)
  
  
• Non-weapon objects of CR 4 or higher may be enchanted with +'s to hitroll, at +1 per CR above 3. This is applicable to all types of objects, worn in all slots.
