Echoing Spell, Spell Perfection and a second metamagic feat

Question

Spell Perfection

Pick one spell which you have the ability to cast. Whenever you cast that spell you may apply any one metamagic feat you have to that spell without affecting its level or casting time, as long as the total modified level of the spell does not use a spell slot above 9th level.

Echoing Spell

When you cast an echoing spell, it does not disappear entirely from memory, and you can cast it one additional time during that day. No effect that allows you to reprepare or recast a spell can affect the echoed spell.

Based on these, is the following sequence of actions legal?

Pick a 5th level spell as your perfected spell Prep and cast the perfected spell, applying the Echoing Spell metamagic feat to it. The spell is still available to cast.

Here is what I'm not sure about.

Cast the echoed spell, applying a second, different metamagic feat to the echoed spell. Specifically, I want to know if I could apply the Quicken Spell metamagic feat so that I could get two castings of my perfected spell in one round with only one spell slot.

Answer 1

If i understand your plan correctly, then yes.

• Standard Action : level 5 perfected spell + echoing spell

• Swift Action : level 5 perfected spell + quicken

The second casting would, of course, consume the slot.

Also, you may want to keep in mind (and somewhat unrelated) the casting time of the spell in question.

Answer 2

You can't have a 5th level spell that is both Quickened and Echoing as the spell's effective level would be 12 (5+3+4) violating the limits on total modified level of the spell. Echoing allows you to cast the same spell again as an "echoed" spell thus the echoed spell remembers that it was once echoing.

Additionally you likely (though this is less strictly supported) cannot add a free metamagic feat to the second casting regardless of spell level as you are casting the same spell one additional time. This means that the second casting of the spell is Echoing (as it is the same spell as the first casting) and echoing is likely considered the free metamagic that you get from spell perfection.
