You can only use non medable armor.
Each resist can go up to 5 higher.
Each piece can get 1 increase per resist.
You can't use invulnerable and do 5 on one resist. It does one on each resist.
You can refine a piece over and over. It resets the piece and re refines it.
You can not remove all the refinements once done.
You can not refine transmoged items.
You can not transmog a refined item.
You can not put mage armor on a refined piece.
Use the amalgamator to increase the value of a refinement.
So no you can not refine 1 piece and get 73 fire resist.
You choose which resists you want to set If you use Protection you will choose your first choice and second choice. You will always get the first choice. 50/50 for the second.

An Elf can have 75/75/75/75/80 resists with refinements, assuming 5x refined items and all hit for all 5 refine resists. Pray to the RNG.
No need to pray Invulnerable does +1 to each resist. Most PvM do not do that. We dont need poison or cold increased.
Smartest for PvM would be just do Physical and Fire to +5. You dont always get 2 with Protection, But you can do it over and over until you do. That would require 5 pieces to be refined.
