Puzzle -
- Standing on the symbol reveals the Ethereal Plane for as long as the creature isn't moving.
- An Ethereal Filcher waits for someone to enter and attacks them using Night's Edge, leaving the Dagger inside the creature.
- If the creature dies on the Ethereal Plane they can't come back to the Material Plane, In order to come back they simply need to move.
- If the creature moved with Night's Edge stuck inside them, they carry it to the Material Plane on their person.
- On the Ethereal Plane there's a tied Banshee, she can't speak because her bottom jaw is torn and her tongue dangles from her throat.
Freeing the Banshee makes her grateful, she will then follow the group who rescued her and will revive one person who dies, once. Afterwards she will disappear forever. - Solved
