Perhaps berrys can reduce the damage done from confusion damage if the inteneded attack was a type that a resist berry would lower? (I.e. Confused Shuca Heatran using Earth Power)
Just wondering if anyone knows of what specifically triggered it and if it is in Gen V or not.
Alder: N, even if we don't understand each other, that's not a reason to reject each other. There are two sides to an argument. Is there one point of view that has all the answers? Give it some thought.
