[QUOTE="Cheiromancer, post: 3048238, member: 141"] [i]Antimagic shell[/i] is a 6th level spell and affects a 10 ft. radius. To cover the earth it needs to be widened 22 times in a row. Each widening is +3 levels. 22 x 3 is 66. 6+66 = 72. That's too much- the benchmark for destroying a planet is 40, not 72. But if only half the +66 modifier were added to the base of 6 we'd get 6 + 33 = 39; almost exactly our target of 40. So I hypothesize that 2 levels of metamagic = 1 level of epic spell. [i]Disintegrate[/i] is a 6th level spell and affects a 10 ft. cube. To destroy the earth it needs to be widened 22 times in a row. Each widening is +3 levels. So the final level would be 72 (again, higher than the target of 50) but we halve the +66 modifier, as before to get 39. This is too low (we want 50) and furthermore is the same as the [i]antimagic planet[/i]. It should be 10 levels higher than that spell. So I posit that a planet should get a saving throw against [i]disintegrate[/i]. Maybe 20 levels of Heighten Spell needs to be added to the mix in order to overcome this saving throw. This +20 is also halved, of course, since by hypothesis 2 levels of metamagic = 1 level of epic spell. This makes the end result 49, which is pretty nearly what is desired. So I am halving the level modifier added by metamagic feats. Otherwise my DCs come out way higher than your benchmarks. But even halving them is not enough for spells like [i]move galaxy[/i]. So I wondered if perhaps I should have been dividing by 3 instead of 2. Or would you say that the 1=1 formula is right and thus your benchmarks are too low? That's what we were chatting about the other day; remember when we calculated that [i]teleport city[/i] would be a 45th level spell? [/QUOTE]
