I'm confused by the magic armor chart in the DMG. Some of the abilities are listed as adding an equivalent ehancement plus for the market price, which you can use to calculate the cost of further enhancements and the limit on the total. However, some just list a straight cost. How do these special abilities work? Do they apply to the +10 limite somehow? If so, how? Do they always cost the same to add to a suit of armor? Do they not increase the cost for further ehancements? Thanks.
