So, Animal Growth (5th level) gives the bonuses of a size increase from the Monster Advancement rules, while Righteous Might (5th level) gives about half that. Meanwhile, Enlarge Person gives significantly worse bonuses and is 1st level.
I'm writing a 2nd-level maneuver that can be used both by a martial adept on his animal companion and vice versa; what stat adjustments should I be giving? It only lasts 1 round.
