Slaved said:Why? Because you are giving the Armor a lot of abilities that the Bracers of Armor do not have and increasing the price DRAMATICALLY WITHOUT PURPOSE!!
How many Classes are actually hindered by Arcane Failure in Light Armor? How many of those can simply Cast Mage Armor?
You are taking overpriced option after overpriced option and putting them all together to make a horribly useless item that no Character in their right mind would ever want and then using it in a comparison!!
A Pearl of Power 1 has a price of 1000 Gold Pieces and it can give that Wizard an extra Mage Armor a day or a lot of other options. Putting the price of Bracers of Armor +4 at 1000 Gold Pieces to simulate the cutting away of the options for a more consistent Bonus makes sense!! Doubling the price can be done as well but that sucks with this comparison and is not necessary.
For a comparison the twilight and ghost touch are the necessary enchantments to simulate having +5 AC from normal armor. This is a legitimate comparison. The pearl of power is a valid option, but does have its own draw backs. Those being that it is now a buff rather than an item. This means that the effect is vulnerable to dispelling effects.
The pearl option is great for a wizard, but only a wizard. Since sorcerers cannot use pearls, and monks do not have spell casting. A magic item's cost shouldn't be reduced because it doesn't make sense in one case.
