My pet currently has 35 AC with enhancements.
Today, when I equipped a +2 docent of reinforced armor +3, it did not affect its armor class.
Last night, when I equipped the same item, it increased its armor by 1. I was unsure whether reinforced armor stacked with the +2 enhancement, but in either case, I expected at least a bonus of 3 from this.
Does anyone know why this is?
