Description
The spellcaster channels the latent energy of a gemstone into a devastating touch. Make a melee spell attack against a creature within reach. On a hit, the target takes 1d6 damage of a type determined by the gemstone used (see below). Unlike many spells that their power is based on the spellcasters level this spell is based on the value of the gemstone. If the gemstone is worth more than 100 gp, the spell deals an additional +1 damage per 100 gp of the gemstone's value (up to a maximum value of 2,000 gp for +20 extra damage).
The damage type is determined by the gemstone:
Sapphire: Lightning damage
Ruby: Fire damage
Emerald: Poison damage
Diamond: Piercing damage
The gemstone shatters upon casting, scattering radiant shards that vanish moments later.
