Another element of lost magic came our way, this time from Denver Edwards. This one has more of a metamagic element to it, which you might embrace in your game as is or soften through the use of more story elements. If you’re the GM, ask the player to describe how the caster’s knowledge of this ancient lore plays out in the mind’s eye during casting, for example, which can help you build more lush world detail into your game, plus personalize that character’s casting style and define what others see when this character casts spells.

By pronouncing an ancient syllable first spoken at the dawn of creation, you instantly know the optimal way to modify your next spell in a way you desire.
You can add any one metamagic feat (you do not need to know the feat) of your choice to the next spell you cast before the beginning of your next turn without increasing the spell level or casting time, so long as the total modified spell level of the spell is not above a level you can normally cast.
The list of metamagic feats you can choose from is based on your caster level. At 5th level, you can select metamagic feats with a +1 spell level modifier. Every four caster levels, the spell level modifier of the metamagic feat you can choose from increases by 1 (+2 at 9th, +3 at 13th, to a maximum of +4 at 17th).
At 17th level, if you select Quicken Spell to modify a spell, you can cast that spell as a free action if it is cast before the beginning of your next turn.
