Good article. One thing I'd like them to think a bit more about, though, is monster weaknesses. For instance, the hook horror uses echolocation to find its prey. This means it's blinded when hit by a silence spell, but also - are there other ways to blind or befuddle it? Use bard song, make loud noises to confuse the echo... Giving the PCs ways to overcome the special ability if they use their brains.
