Banishing Light

You attempt to banish one creature that you can see within range from existence. The target must succeed on a Charisma saving throw or be destroyed entirely. If the target has 0 or less HP it immediately fails.

"It haunts me to this day to think that Sionn is still out there. The others think I'm crazy, but I know he'll return. I must prepare. I must make up for our mistake of letting him go. I will find some way to channel the greatest of holy energies to ban this shadow from existence. I will create a Banishing Light".
