Embue

Embue a Gem with a Spell that can be cast once per day without using a spell slot. All rules for said spell shall remain.  Spell cannot be scaled. Must be able to cast the spell in order to embue it. Casting time is 1 hour per spell level being embued. Spell success is 65% reduced by 5% per spell level being embued. A failed attempt results in the destruction of all components. For example, to Embue Fireball  at level 3 into a gem, it requires a Gem worth 1500 gold, a small ball of bat quano and sulfur, 3 hours casting time and 50% success roll.  At higher levels, the success chance increases by 5% every 2 levels above 4th
