I'm a little unclear on what fighting with the weapon kata trait is supposed to represent.  When using weapon kata am I still considered to be making unarmed attacks?  If I attacked an enemy that does damage if I touch it (say a fire elemental), will I still take damage?  If I use spells that buff my unarmed attack (e.g., Touch of the Grave from black magic or Chi Focus from the Monk school of magic) will it buff my weapon kata attacks? If I use spells that buff my weapon (e.g., a Warrior Mage's Storm Shock) would that buff my weapon kata attacks?
