Choromancy Master

As a Master - spell casting became a metamagic feat for that caster, allowing them to weave magic, and spells beyond their abilities.

As a Master, you can create Spell Gems.

There were several types of gems that could store spells. In order of the power of spells they could store, from your own Spellbook the gems were:

• Obsidian 10gp, cantrips only requires a Short Rest
• Lapis lazuli 10gp for a level 1 Spell, requires a Long Rest
• Quartz 50gp for a level 2 Spell, requires a 2 Day Rest
• Bloodstone 50gp for a level 2 Spell, requires 4 Days Rest
• Amber 100gp for a level 2 Spell, requires 6 Days Rest
• Jade 100gp for a level 2 Spell, requires 8 Days Rest
• Topaz 500gp for a level 2 Spell, requires 12 Days Rest
• Star ruby 1000gp for a level 2 Spell, requires 18 Days Rest
• Ruby 5000gp for a level 2 Spell, requires 24 Days Rest
• Diamond 5000gp for a level 2 Spell, requires a 30 Days Rest
• Chardalyn(Minimum value of 10000gp) - Level 10 Spells - Unknown .....

These Spell Gems, don't require/use spell slots when used, and once used, the Spell Gem turns to dust.
