Can my wizard create ritual spell to lift an entire mountain five hundred feet into the air permanently? If so, what level would it be?
I don’t know; can he? Since I don’t know of wizard succeeding at such a feat, I can’t say that it’s definitely possible, and no one knows for sure what’s impossible, so the only way your wizard is going to find out whether it’s possible is to try. As to the ritual’s Level, it would sure be high. Floating a mountain violates its nature, so that’d be a difficult maneuver. A Level 50 ritual can cause a tidal wave, but that’s a natural and temporary phenomenon. The floating mountain trick might be Level 100 or Level 200 or Level 1,675. Again, there’s no way to know until your wizard tries it. Hermetic theory is not predictable enough that we can know ahead of time what Level a given effect is. The real problem is that your wizard may think he’s succeeded, only to have the mountain come crashing down in a week or so. That’s the problem with experiments on such a grand scale: when they go awry, watch out. Even if the ritual succeeds, it could have unforeseen consequences of major proportions
