Mastery of the Silver Void

(Player's Guide to Eberron, page 126, DnD 3.5)

[General]

You have gained a deeper understanding of the Astral Plane and its relationship to the other planes of the cosmos. You can use that knowledge to more quickly access that plane.

Prerequisite

Quicken Spell, Knowledge (the planes) 6 ranks, Spellcraft 12 ranks

Benefit

Three times per day, you can spontaneously apply the Quicken Spell metamagic feat to any conjuration (teleportation) spell you cast. Doing this has no effect on the spell's level and can be done even by spontaneous Spellcasters; however, it reduces your caster level for the spell by 9 (which likely reduces the number of other creatures you can affect with the spell).
