If casting spontaneously, I can spend 1 point from my arcane reservoir to add a metamagic feat (that I know) to the spell without increasing it's casting time, but still using up the higher level spell slot? (This seems pretty straightforward.)
Alternatively, if casting a prepared spell that was already preped with metamagic, I can spend 1 point from my arcane reservoir to add another, different, metamagic feat effect (that I know) without changing it's level?
(ex: I prepare a Stilled Fireball as a 4th level spell. I can then spend 1 arcane point to make it a Stilled Quickened Fireball out of the 4th level slot?)
(This is less straightforward, but this seems to be what the ability is reading as.)
Do I have it right?
IMO, both cases are the same.
The exploit is just making it clear that in both cases the Casting Time doesn't increase, but you can add Metamagic feats to Spells wit and without them, but you can't add the same Metamagic twice.
Otherwise adding a Metamagic feat for free (no casting time increase nor spell level) would be way too op.
Okay, I see what it's saying now.
I was seriously over-thinking it! lol
Thanks!
