The Delay Blast Fireball

Geralt: "I raise the Umbrr staff and I say bad news, idiots" The poem establishes that this takes place after everything else that's happened in the morning. Each creature in a 20 foot radius sphere centered on explosion of flame must make it dexterity saving throw. If you don't save it goes bad. We'll just do this next day saving throw now. And then just as quickly as that, they're gone.
