HI. Is Spellfire “Raw magic” the same as Silver Fire “pure weave” magic? Yes and no. Same stuff, but if spellfire is a gout of flame raging up out of a bonfire, silver fire is a precisely-adjusted blowtorch flame (specific shape and temperature). Spellfire is raw Weave energy, silver fire is Mystra-granted ability to channel the Weave.#Realmslore

I remember you speaking on silver fire being able to damage and/or destroy Larloch due to his Lichdom and prevent him from escaping to the weave to reform later. I assume that Spellfire would be more damaging and same result. Yes. More damaging as it's like a flamethrower rather than a blowtorch.
A blowtorch's flames go pretty much where you want them to, but a flamethrower sprays a far less precise area.
So spellfire's more damaging to the local Weave, whereas silver fire's more surgical.#Realmslore
