To my understanding, he said, if you use say a fire wand to do fireball on an ice element monster, then you'd do extra damage. But if the enemy is a different element or you use a staff that little extra damage won't be counted. But that isn't a damage debuff, more like a lack of a boost. And that's not to say the damage increase by using a staff is greater or less than the elemental increase. (Just my interpretation, not sure.)

^ yes, this was what I was trying to say.
