Sometimes, your players may be a little bit too familiar with the Monster Manual. There may come a time that you're no longer able to surprise them with the creatures available there, or maybe they're just too genre savvy and they can already guess the weaknesses of the encounter you've built.
Why not keep them on their toes with a series of brand new monsters, which they've never seen before? And while you're at it, why not spice up the idea of the centaur, which everyone has come to know and love. From adorably charming woollings (halfling-sheep) to fearsome ursidines (orc-bears - that's right, orc-bears!), this supplement will surprise and delight your players with 15 all-new creatures.
