Cold Gem (3.5e Spell)

You breathe cold onto the sapphire in your hands, and it begins to glow an icy blue.

The gem deals 1 point of cold damage per round to creatures and unattended objects (other than itself) in a 10 foot radius spread. For every hour that the gem has been affected by this spell, the cold damage per round increases by 1 and the radius increases by 10 feet.

If the gem is destroyed, the spell ends. The gem is diminutive, has 1 HP, and has hardness 10.

Focus: A sapphire worth at least 50 gp.
