Claws of Gems

You use the gem dust to create sharp blades on the tips of your fingers. When the spell ends, the blades return to dust and can be used repeatedly.

add 1d6 piercing damage to an unarmed strike. Add another d6 at 3rd caster level and every two levels after.

when you reach caster level 10, you are able to change the damage type based on the type of gem dust used. At least 80% of the gem dust used for the spell must be of the specific type of gem you wish to benefit from.
