Read moreThat's correct. I suggested a melee skill, upheaval and replaced the physical tag with a cold tag, and specced pets into cold tags. That way you just throw cold damage wherever and the player's melee, along with pet spells, all scale. If I understand correctly, both melee and cold melee on OPs item would scale upheaval, which would then be scaled more with shared cold damage affixes. Minion spell damage on item would scale pets cold spells along with shared cold damage as well. The bleed would turn into frostbite from the upheaval, which is a cold dot and I believe shred cold resist, making pets and upheaval that much more efficient and I believe the DoT from frostbite would scale up from cold damage as well.
Edit: u/ekimarcher is my understanding correct on the scaling of cold upheaval? All other stats aside. The item above is 130 base melee and 88 cold melee. Say upheaval is purely cold, but still scales off melee tags. Would increased cold dam...
All added damage is added to base. Added melee damage (weapon implicits) is converted to cold if the ability in use is pure cold. (Split at whatever the base damage ratio is for multi element).
Add all increases together and apply. Increased cold damage applies to all the cold damage, which in your scenario is all of it. Generic damage increases apply to damage.
Apply all more modifiers individually. Same rules as above.
