New Elementalist Spell: Crystal Resonance

It ain't all just "fist of flame!!!!!!" in elementalist world.

Crystal Resonance
Level: 1
Duration: Special
Range: 30'
Casting time: 1 turn
Elements: Earth

A specially attuned crystal (costing 75gp), in combination with this spell, allows the elementalist to absorb certain energies from his surroundings. Once an energy has been impressed into the crystal's resonance, a second casting of this spell causes it to reproduce the stored energy in whatever environment it now occupies. One of the following energies may be absorbed into the crystal:

• Light: the lighting qualities of an environment may be absorbed and reproduced, causing an area of light, gloom, shadow, and so forth to be emitted from the crystal for 1 turn per level of the caster.
• Images: a static snapshot of the crystal's environment can be attuned for later examination. The image is reproduced for 1 turn.
• Sound: any sound emitted during the 1 turn casting time may be recorded and reproduced.
• Temperature: warmth or cold may be absorbed into the crystal and re-emitted for 1 turn per level of the caster.

A crystal which has been attuned with this spell retains the absorbed energy indefinitely. Each crystal can, however, only be attuned to a single energy – subsequent attunements will replace the original.
Each time this spell is cast, there is a 5% chance of the crystal shattering and becoming useless.
