Make dat Wolf a Rune Knight!!!There's an issue with beasts
Real beasts are boring on purpose
Real animals have what I call "palette swap" issues. Real animals are not interesting in combat. They are mostlyeither tough brutes, fast brutes, strong brutes, flying brutes, swimming brutes, or brutes with extra attacks. They are much like the same 4e-style stat block leveled up or down and given a level and given an movement quirk or extra senses. 3 versions of the same bears, canines, raptors, and felines.
That being said, there are somethings you can still do. There are lesser used animal families like weasels, hippos, skunks, mongoose, and large lizards that are not heavily used.
