I'm a bit confused about the rules on adding Magic abilities to Armor. I wanted to buy a +1 Mithral Chain Shirt with Light Fortification (listed as a +1 bonus cost in the book) . To my understanding the cost would be broken down as follows.
Chain Shirt (100 g)
Mithral (1,000 g)
+1 Bonus (1,000 g)
Light Fortification (1,000 g)
Cost = 3,100 g
According to the GM I was dealing with at the time, the Light Fortification would cost me 4,000 g because I would need to pay for it at a +2 bonus cost because I already had a +1 factored in to the price. Making the total cost 6,100 g. I'm actually really cool with the GM and consider him very fair and knowledgeable of the rules, I just want to confirm this before I start holding other people to the rule in games that I run.
