As I've said, Magic should be in the game but in the way you've treated the smoke particle. People would have to go out of their way to enable it, same if it was an ingame feature. People would have to slave away to make magic useful and practical. I guess only modded worlds or specially tuned worlds could have them.
The results are also interesting, which I like. I'm glad people desire monsters within reason. Rising World still needs to live and breath; Rising World needs to breath on its own so it can allow us to play along side it as we nudge things into our direction.
