You place a small spark of energy in the heart of a valuable gem.
You turn a gem into a bomb that you (and only you) can lob at enemies. You must hold the gem in your hand when casting the spell. You can toss the bomb with perfect accuracy anywhere within 60 feet. The gembomb explodes in a 5-footradius burst dealing 1d8 points of force damage per two caster levels (maximum 5d8). Tossing a gembomb is a standard action.
Material Component: A gem worth at least 1 gp.
