When providing battle support, units offer AVO, which is Avoidance. I know it directly lowers enemy's chance to hit.
But units can also increase DDG. I can't find anything in the in-game help about what it does, or what it stands for. Presumably, it's meant to be short for Dodge, but I've seen supports offer both AVO and DDG, which leads me to believe that's not what it is.
What is DDG, and what does it do? If it differs from AVO, what is the difference?
