I've tried a few times to use Staff of Beasts, but ultimately came to the conclusion that it was just not a good option. The Johktari Hunting Knife looks like a much better deal. It's more action efficient, it costs less, and while it puts some constraints on activation order, it's an efficient means of boosting damage output, whether with a swarm or with a few bigger creatures. It works well with creatures that are guarding, and combos particularly well with Defend. I'll probably be switching my Straywood Beastmaster's weapon out for this when I get my hands on Academy.
