I'm not sure about the order : I 've made a test now with EDM adn my UD-forged trader falshion in 2.4
Seems the physical and the divine were multiplied correctly * 4 , while magic was only *2 and electric was not multiplied. And the char sheet shows a different order : https://imgur.com/a/1R1r1c5
I did another test, using a fighter falshion UD forged (with +2d8 divine and sonic).
I had EDM on, equipped the falshion (so the EDM bonus was at top of damage list in CS) then the crits were multiplying divine and physical, magic was barely multiplied by unknown factor. Result : https://imgur.com/a/tnEgJWQ
Then I rested, so EDM disappeared from the top, then EDMed, and then only magic and physical and positive (which is far in the list, and comes from set bonus) are multiplied : https://imgur.com/a/Pbxcbdw
how to interpret this ?
