Empower affects variable numeric effects.
Enlarge affects range. (and area of effect I think)
Quicken affects casting time.
All three affect three different things, so the effects apply to the whole spell.
Maximize affects variable numeric effects. Which is why it doesnt enhance Empower as well.
Make sense?
That would make sense. But that isn't the rule they gave us. By saying metamagic always effect the base spell you have these results.
Empower a cone fo cold base spell(current level 10) x1.5 for the 10d6. Range is short. AoE cone, so 25ft+5ft a level(75ft). That is what gets empowered since that is the base spell.
Enlarge effects range(including AoE defined by range like cones) it doubles the range. Again it effects the base spell or (25ft+5ft a level)x2 so now the range is 150 ft. 75 of which gets empowered, since the empower only effect the base spell which is a 75' range.
confusion can now ensue on the quickened, silent, still Magic missile. A nice 7th level spell.(quite weak actually even at its best interpretation)
quicken apply to base spell, its now a FA. the base spell that is.
Silent the base spell is now silent
Still no somatic on base spell.
How do they interact. Does the order matter?
You can come up with 2 interpretations one makes it a Free Action silent still spell.
The other says well the silent and still aspects are applied to a SA spell, and the quicken only quickens the base spell not the modified spell. So the spell fizzles, or its a free aciton to cast the magic missile, but a standard action to keep it silent and stilled.
By saying it always applies to the base spell instead of the modifed spell more problems result than were fixed. the only legitimite problem I can see is a extened, persistent spell. And easy fix is to say hey look they don't stack, ones a pre-req, and there the same effect just ones more potent.
