I could redistribute the stats, adding 5 to Intelligence and 10-20 to Willpower (or 5 to Intelligence, 10-15 to Willpower, and 10 to Agility), but would it be viable? Is it worth it for a single spell that hits once and consumes the entire mana pool in three casts, especially when you're already planning on having a hundred damage dealers?

Well, I mentioned it more to avoid wasting a third of the mana pool. Unless you're counting on bonuses from leader-standard bearers. (By the way, does leadership even affect puppets?) If anything needs to be changed, it shouldn't be the stats, but rather the arrow itself – replace it with telepathy/portal/healing. (unless you need to hit an ally with it, lol)
