Lava Release: Rubber Wall

The user creates an enormous torrent of lava from the ground directly in front of them, which can then provide additional support to a pre-existing barrier when layered atop of it. As the lava that covers the barrier only partially hardens, it gains a rubbery consistency that allows the material to deform when attacked, meaning it can both absorb and dissipate the force behind a blow rather than just simply obstructing it.
