How Neutral Damage + Elemental Damage Work In Spells

this a question for a gm
say i am a mage
i have 200-200 neutral and 200-200 fire
i meteor
than for some reason i do like 100 neutral damage and the rest is elemental
now why is that?
i mean clearly my neutral damage is over 50% , meteor converts like what 30% fire and 30% earth damage
why does it convert all neutral first and doesnt take it equally from elemental and than neutral?
is this supposed to happen?

 

I have the same "problem". I am an archer who has 300~ Neutral and 500~ Earth. I have no spell damage modifiers, neither raw or percents.
Yet my arrow bombs do NO NEUTRAL DAMAGE and 7k Earth.
Same with arrow shield :/

 

To my knowledge, skill points convert some neutral to elemental, and the elemental in the spell itself is a bonus, not a conversion.

 

I think the spells themselves have something to do with it, When I use Smoke bomb with my thunder/air assassin It deals Earth, Fire, And sometimes Water damage with Air and Thunder
