D&D 5E The Monsters Know What They're Doing (5e)

[Nebulous]

I'd like to see what he would do with the Expanded Monster Manual, although it's really just an extension of all the tactics already laid out with far more advanced monsters than the default MM. If you don't have the Expanded Monster Manual I highly suggest any 5e DM pick it up, it's what any official WotC Monster Manual 2 should have been, adding layers of variety far exceeding what we got in the base game.
