I don't have Blackmoor to hand, but I wouldn't be surprised if they stated where the technology came from, so that argument probably doesn't hold water.That is, both of these things were part of their respective settings from day one, so far as the consumer was concerned.
Nah, average Forgotten Realms peasant doesn't have low level spells as a commonly accessed thing. Bottom-heavy magic is worse than top-heavy magic in this instance.You can say this of many campaign worlds, especially Forgotten Realms, which is loaded with high-powered magic, gods walking the earth, mortals meeting with and turning into deities, etc.
