Quicken Summoning (3.5e Feat)
From D&D Wiki
Quicken Summoning [General, Metamagic]
This allows the caster to summon creatures more quickly.
Benefit: The casting time of any summoning spell is shortened to one standard action but the spell level goes up by two levels.
Normal: If the character doesn't have this feat, then the casting time for any summoning spell is as it says with the casting time.
