Maedar and Iron Golem (Patreon)

The maedar is interesting. I tried to make something that made sense in a medusa's lair and added another threat vector for players. I got rid of the Glyptar mechanics, though, since they happen on a time scale that makes them kind of irrelevant for a game of D&D. 

For the Iron Golem, my goal was to make it possible for a party without magic weapons to fight it. Nonmagical weapon immunity is a cool idea, but practically it just means that DMs don't use those monsters against parties that can't hurt them, and the trait ends up being kind of meaningless. Hopefully with some other weaknesses, the Iron Golem can be used as Gygax intended: to terrorize mid-level players with its apparent invulnerability.
