Gemsmith
Every single object in this world has a connection to the weaving energy of the arcane. A Gemsmith knows this and it is their job to bring out the true potential of the pieces of the world around them. They imbue, alter, and create magic jewels brimming with arcane power right before your eyes. The process of creating these magic storing jewels is a well kept secret of the trade but those who have mastered the crafting of gems can find themselves holding a great amount of power in the palm of their hand.

Spell Crystallization
At 3rd level, when you take a long rest, you can use your Jeweler's Tools on a simple rock, piece of glass, or small object and transform it into a beautiful Arcane Jewel that is brimming with magical energy. When you create an Arcane Jewel you can cast a spell from the Artificer spell list that you currently are able to cast, and store it in the jewel, without expending a spell slot. The spell has no effect, other than to be stored in the Arcane Jewel. Arcane Jewels, although beautiful, are worthless and easily recognized as an impermanent stones by any creature.
While touching the Arcane Jewel, a creature can cast the spell stored within it. The spell uses your slot level, spell save DC, and spell Attack bonus as well as your spellcasting modifier. If the spell requires concentration, the creature who activated the stone must maintain concentration. but is otherwise treated as if the creature cast the spell.
Once an Arcane Jewel is used to cast a spell it loses its stored arcane power and reverts back to its basic form and can no longer be used. When you use this feature to create an Arcane Jewel you can create additional jewels by casting the spell to be stored and expending the appropriate spell slot. You can create a number of Arcane Jewels equal to your Intelligence modifier. All Arcane Jewels you have created lose there stored spell and revert back to their basic form when you take a long rest.
Imbued Casting
At 5th level, your infusions radiate with power and aids any creature that comes in contact with your magic items.
Once per turn, if a creature is attuned to an item you have infused and they hit a creature with a spell, melee, or ranged attack you can add additional 1d4 force damage to the roll.
Arcane Optimization
At 9th level, you have learned to enhance and optimize the spells you store in your Arcane Jewelery. When you store a spell that has a casting time of 1 action you can choose to improve the spell and change the casting time to 1 bonus action.
You can use this feature a number of times equal to half your proficiency bonus and you regain all uses after a long rest.
Explosive Spellcasting
At 15th level, as an action, you can give any creature within a 60ft radius of you with an Arcane Jewel the chance to activate it. Any creature in range that has an Arcane Jewel can use their reaction to cast the spell stored within the Jewel.
Once you use this feature you do so again until you finish a long rest.
