I wouldn't mind being able to give a warrior's greeting hug to a friend when I see him and haven't chatted for a while. Perhaps a Charge abillity:
Action: Player would rais his arm and launch into a fast sprint roaring "Charge!"
Effect: +130 Damage. -15 Recycle Time. -8 Delay. +78 Armor. +33 Magic Defense.
Recycle: 50 Minutes.
