10 story portal

A wide portal appeared on the ground then and the Humbaba fell backwards into it, reappearing high in the air above us—and wide open as I gathered my power anew. Drawing from my HP and MP both, I gather light between my fingers and in a trio of orbs around each wrist, before lighting up the sky and tossing the creature back through the portal it had come from and making a massive column of light rose from the portal on the ground and straight back up to the one directly above it.
