My question is this: Can I apply a skill requirement (-10%), an alignment requirement (-30%), and a class requirement (-30%) for a total of -70% crafting cost?
The DMG lists options available to players for reducing the gold cost when crafting items:
Other Considerations: Once you have a final cost figure, reduce that number if either of the following conditions applies:
—Item Requires Skill to Use: Some items require a specific skill (such as Perform for a musical instrument) to get them to function. This factor should reduce the cost about 10%.
—Item Requires Specific Class or Alignment to Use: Even more restrictive than requiring a skill, this limitation cuts the cost by 30%.
It is ambiguous because of the wording of the section -- I cannot tell if it is saying:
- You may either apply a 10% skill restriction bonus or a 30% class/alignment bonus
- You may apply both a 10% skill bonus and a single 30% bonus from class/alignment restriction
- You may apply a 10% bonus from skills, a 30% bonus from alignment, and a 30% bonus from class restrictions
