I have come to ask for a new Transfigured Molten Shell

Many years ago, prior to the 3.7 changes to Guard Skills, there were builds that revolved around using Vaal Molten Shell as their primary source of damage. I would like the chance to revisit this play style, so I ask that a transfigured gem be added to mimic the effects of the old Molten Shell:

Molten Shell of Thorns

The damage from the explosion would no longer be "reflected damage", would have it's damage effectiveness multiplier and critical strike chance restored, and would also be able to scale with sources of increased/more damage.

Rather than reflecting damage taken once per second, the explosion would proc when you take damage from a hit.

As for the base damage, it could be a flat value baked directly into the gem, or it could be based on the value of the buff it grants you from your Armour. More Armour = more damage, up to a maximum value of course.

I would entirely understand if the defensive aspects of the skill need to be weakened or even removed in order to justify the offensive changes.

My favorite build that I ever made was back in Incursion League, and it involved a complicated Rube-Goldberg machine of unique items and mechanics to optimize this skill. I desperately want to give it another go.
