Deepest apologies to all my impatient readers. Between doing revisions on The Monsters Know What They’re Doing: Combat Tactics for Dungeon Masters and taking care of a daughter who’s just starting to get the hang of a nap schedule, I haven’t had time for blogging. And this particular post is a mother.
The drow matron mother, CR 20, is second only to Lolth herself in the drow boss hierarchy. She’s a spellcaster first, a skirmisher second, certain to be surrounded by a multitude of minions. She’s also a legendary creature, with legendary actions—one of which she can turn over to a demon ally for its own use, sort of a drowish Commander’s Strike.
Like all drow, the matron mother has Fey Ancestry (passive), Sunlight Sensitivity (no going outside, especially during the day), and the innate spells dancing lights, darkness, faerie fire and levitate. However, she’s got a few additional tricks up her sleeve: She can cast detect magic at will, and once per day, she can cast clairvoyance, detect thoughts, dispel magic and suggestion.
Note that the matron mother can cast dispel magic with or without using a spell slot, but when she casts it innately, it works only against spells of 3rd level or lower. Since she can cast it this way only once per day, she’s going to be finicky about what spells she dispels with it, saving it only for the most important. A very good candidate is invisibility, since dispel magic affects “one creature, object or magical effect” within 120 feet and doesn’t require her to be able to see the target, only to know they’re there. Pop! Haste, slow, hypnotic pattern, enlarge/reduce and spiritual weapon are also top choices. If she wants to dispel anything else, she’ll spend a spell slot on it.
