The class of spell the system calls an Atrocity, of which Donut's War Crime is one.
Carl wrestled with the classification in his Cookbook note: the system calls Donut's War Crime spell an "Atrocity," and the dictionary in the guildhall defines that as an act of fiendish cruelty. He wonders whether the definition is unfair, or correct but wrongly applied — or whether the true act of fiendish cruelty was giving her the spell at all. That such a spell came out of the same Legendary 1914 Box as Spellbook of Run, Little Günter, Run only makes the gulf in capacity between them more astonishing.
The spell tier that gives Carl's plan its power and its moral cost.
