Accelerate Metamagic( Races of the Dragon, p. 98)
You can apply a selected metamagic feat to your spells more quickly than normal.
Spellcraft 4 ranks, ability to spontaneously cast 1st-level spells, any metamagic feat, Dragonblood subtype,
Choose a metamagic feat you know. You can apply the selected metamagic feat to any spontaneously cast spell without increasing the casting time.
You can gain Accelerate Metamagic multiple times. Its effects do not stack. Each time you take the feat, it applies to a new metamagic feat.
Without this feat, metamagic spells with a normal casting time of 1 standard action take a full-round action for spontaneous casters. Metamagic spells with a casting time of longer than 1 standard action take spontaneous casters an extra full-round action to cast.
