Arithmetician

Calculator is a job class from Final Fantasy Tactics. Calculators are capable of targeting groups of characters that meet certain criteria with most spells (for example, a Calculator can target all characters whose levels are a multiple of 3 with Fire4, or target all characters who are standing on a Height level that is a Prime Number with Cure3). While this can be a powerful tool when opponents have spread apart, it can also be a curse as allies will also be targeted if they meet the chosen criteria.
