Enhancing a weapon with valorite....damage?

[Coragin]

Okay so I am reading enhancing with valorite adds all 4 elements.  Here is my question....

When using a weapon with all 4 elemental types, against something that has a 0 against one of them, say cold like fire lementals.  Will you get the full dmg as if you were using a 100% fire weapon?  Or just 20% of the damage will be full?  Can anyone explain to me in detail how this works?  Does it take the resists on the weapon the creature is most vullnderable to?  Or does it use ALL damage types even if the target is immune?

It's all broken down. If a weapon does 20 physical, 20 fire, 20 cold, 20 poison, 20 energy against a monster with 40/30/70/50/40 resists, then the total damage is split up first then applied against the specific resistance to give the damage inflicted.

Say your total damage output is 50 points, and your weapon is 50% poison and 50% fire. That means 25 points damage against the opponents poison resist, and 25 points damage against the fire resist. Depending on how much resistance they have is what final damage you apply to them.
