More ways for Druids to make Molten Fissures? (for Rolling Magma)

I misread this skill initially and was excited to use Rolling Magma+Entangle. The only non-Mace skill that creates them currently is Fury of the Mountain... And I dunno, I'm attached to the fantasy of casting as a human.

Random suggestions:
- Support Gem that converts Fissures to Molten Fissures.
- Support Gem that adds Molten Fissures to the Volcano skill.
- Add a Primal Spell that creates Molten Fissures.
