Gemcutter's Divine Resonance

You have an innate connection to the divine energies within precious gems, allowing you to enhance your holy symbol's power through careful crafting.

Initial Feat

• You gain proficiency with jeweler's tools.
• You can attempt to enhance a gem for your holy symbol once per long rest.
• Choose one gem type to focus on: Healing, Elemental, Damage, or Utility.
• Your holy symbol can hold up to 5 enhanced gems at a time.

Gem Enhancement

To enhance a gem, make a Wisdom (Religion) check. The DC starts at the level-appropriate value and decreases by 1 for each successful check. Track your progress using the provided Resonance Chart.

Resonance Chart

Fill in the "Current DC" after each attempt and mark failures. When the Current DC reaches 5, you unlock the next level. After 5 failures, reduce the DC by 1.

Progression and Requirements

• Each enhancement level requires the gem listed for that level.
• You must complete all previous levels before attempting a higher level.
• You can work on enhancing multiple gem types simultaneously, but can only attempt one enhancement per long rest.

Additional Rules

• A successful check reduces the Current DC by 1 (minimum 10 for future attempts, but still progresses downward).
• If you fail an enhancement check, the gem's value is halved, and it becomes unusable for further enhancements.
• After 5 failures at a level, reduce the Current DC by 1.
• You can change your chosen gem type when starting a new enhancement, but progress on previous gems is preserved.
• The enhanced gem must be incorporated into your holy symbol to gain its benefits. No more than 5 gems can be used as a focus.  Switching a focus requires attunement during a long rest.
