The molydeus is a demon of extraordinary power, on par with several named demon princes. The flavor text refers to various demon lords as “masters” of molydei, but there aren’t too many entities to which that word could apply, given that demons are chaotic evil and therefore not likely to take orders from anything less powerful than themselves.
The Mordenkainen’s Tome of Foes flavor text notwithstanding, unless and until new demon lords are crowned and their stat blocks published, there are only two that could indisputably command the obedience of a molydeus: Demogorgon and Orcus. (Graz’zt and Yeenoghu are only one challenge rating higher than the molydeus; I’m not sure that’s enough of a difference. Baphomet and Fraz-Urb’luu have the same CR as a molydeus, so even if one of them created a molydeus, I think it would tell them to buzz off, if not turn on them immediately.) For some unfathomable reason, I looked at that “CR 21” I don’t know how many times, and my brain processed it as “CR 23.” Yes, any demon lord is powerful enough to command a molydeus. SMH.
For a huge creature, the molydeus is speedy, with a movement speed of 40 feet. Its ability scores are all extraordinary, with Strength first and Constitution second—a brute. While it has Innate Spellcasting, it’s secondary to melee fighting. It has proficiency in four out of six saving throws, but one of the big three—Dexterity—is missing from the list, so in relative terms, this could stretchily be noted as a weakness. But it also has Magic Resistance and three uses of Legendary Resistance per day, so whenever it fails a Dex save . . . it doesn’t fail.
Typically for a demon, the molydeus is resistant to physical damage from nonmagical weapons, cold, fire and lightning and immune to poison; it can’t be blinded, charmed, deafened, frightened, poisoned or stunned. (It can, however, be paralyzed, knocked prone or restrained.) It has a truly bonkers +21 Perception modifier and passive Wisdom (Perception) 31. Player characters trying to sneak up on one, at a minimum, will need pass without trace. Continue reading Molydeus Tactics
