Balefire

When Balefire is cast a pencil thin beam of radiant energy is cast at a single target within 60 feet. Make a spell attack roll; if the spell attack is successful the target takes 12d6 points of damage. If this spell reduces a creatures hit points to 0, that creature is vaporized and can only be restored to life by means of a wish spell. All allied targets that were knocked unconscious or have been killed since the end of your last turn are returned to life at 1 hit point.

Prolonged use of Balefire is extremely dangerous and can begin to un-write the very fabric of existence. If Balefire is used too much in a given location wild magic zones may be created or tears in the fabric of space/time or to other planes may be created at the DM's discretion.

This spell can be cast using a higher level spell slot. For each level beyond 6th add 1d6 radiant damage and the all allies knocked out are returned to life for 1 additional round.
