For my aetherpunk/magi-tech supers game, I need to create stats for 3 powerful hags pretending to be newly arrived magical girls superheroes (basically, I stole the plot from Morrison's JLA Hyperclan story whole cloth). Each is going to be a Tier 3 Solo (the 5 PCs are 5th level) and I will round out the big final fight with some minions.
I want to create a "coven" power that makes the Triarch (as they call themselves) een more effective when working together -- something akin to the Tag Team ability of the PCs.
APEXA is the physical brute and is secretly an Annis hag. She gives Maxima or Power Girl vibes.
GAIA is secretly a Green hag and has plant based powers. Interestingly, one of the PCs is a Poison Ivy type and so GAIA is jealous of her.
NOCTURNA has umbral and psychic powers and is a Night hag. This thing was her idea, because she wants to get into the heads of all the Triarch's "adoring fans".
What sorts of cool DH translations of traditional hag spells or powers would you use for these characters? How would you build the "coven" ability I mentioned above?
Oh, the PCs are:
Skyfyre: a dracona winged seraph (secret ID: aristocratic debutante)
Riven: an infernis primal sorcerer (secret ID: a cad)
Baseline: a human troubadour bard (secret ID: punk rocker)
Wild Thorn: a human warden of the elements druid (secret ID: gardener to the wealthy)
Citadel: an earthkin stalwart guardian (secret ID: resurrected guardian of the Church)
In this setting, only "supers" have DH classes. Normals can use magic to a degree, mostly in an engineering, magitech kind of way. But PCs (and their villains) are special in the same way they are in most supers settings.
