@TheEdVerse A question if I may, something that has been bugging me for days now: is there an equivalent of spellfire in the Shadow Weave? And if so, who/what were it’s wielders?

No, there isn’t. Spellfire is a ‘wild talent’ way of accessing the raw power of the Weave. That raw power is like a consuming fire when in contact with Shadow Weave magic, so it destroys Shadow Weave spells 2)
Also, because of this, no Shadow Weave practitioner has time/opportunity to master spellfire effects; it's like trying to learn to knit with wool that's on fire and melting in your hands.
Mystra permits spellfire to spread magic use; Shar spreads loss and chaos.#Realmslore
