[VXA]What type of damage influenced by "magic damage rate"?

Hey there,

so, I am brooding over the MDR Sp-Parameter, magic damage rate.
If the PDR stat regulates all damage, that has the "Normal Attack" element, does the MDR just modify the damage of all other elements?
What if I want to have elements like "blunt", "slashing" or "piercing"? These shouldn't be influenced by the MDR, but by the PDR.

Can anyone help me out with finding the lines of code, where these damage rates are handled?
Is there already a way to assign what elements are influenced by the physical and the magical damage rate?

Sincerely

When making a skill or item, there is a section titled Invocation. One of the options under that section is "Hit Type:", and you can select for it one of three things: Certain Hit, Physical Attack, or Magical Attack. pdr affects only those skills which are set as "Physical Attack", while mdr affects only those skills set as "Magical Attack". The elements of the attack have no effect, so they can be whatever you want.

Wow, that was easy. Thanks a lot. 
Guess I should have taken a closer look at the skill settings.

No problem.
