Separate from the action as he was, Sephiroth quickly noticed how the tentacles were repulsed by the tiny lights that lit-up leading back through the tunnel and up into the main room they had come from. He cursed under his breath - he didn't have anything available to use that would flood the watery tunnel with light and potentially stun the monster to enable an escape.

Sephiroth wasn't even sure he could sneak past the monster in the way he's managed so far. Either way, he'd have to find out.

"Light up the cave! We're done here."

He's already floating closer to the others, atop the water's surface -as close to the monster as he dares- squinting between the tentacles to see if he can't judge whereabouts its body should be. If he timed it just right, perhaps he might be able to orchestrate a job switch and get an attack in as he plunged into the water.

So very risky though.
