When not wearing armor or using a shield, a duelist adds 1 point of Intelligence bonus (if any) per duelist class level to her Dexterity bonus to modify Armor Class while wielding a melee weapon.
sithramir said:I wouldn't treat it as anything other than what it is labeled. So its an "unnamed bonus" which stacks with everything else. So a monk duelist would keep ac bonus's from both classes because it never said it was similar so why assume it is?
