PC Class Variations - The Gem-Cutter (Jeweler / Lithomancer) For Baptism of Fire & Other OSR Style games

 Here is a complete, custom character class designed specifically for Baptism of Fire (and fully compatible with Lion & Dragon / OSR systems).

In early medieval Piast Poland, precious stones are not merely luxury items—they are conduits of planetary resonance, signifiers of high aristocratic rank, and essential components in authentic esoteric stone-magic (Lithomancy).

Class: The Gem-Cutter (Jeweler / Lithomancer)

• Prerequisites: Intelligence 11+, Dexterity 10+

• Primary Attribute: Intelligence

• Hit Dice: d6 per level (up to 9th level; +1 HP per level thereafter)

• Armor Allowed: Padded, Leather, Studded Leather (no shields)

• Weapons Allowed: Daggers, Stiletto, Light Crossbow, Club, Hammer, Shortsword

• Social Class Alignment: Tradesman / Craftsman Class (or Townsman). Requires Burghal rights, Guild charter, or royal/noble patronage to practice legally in major castellan towns (e.g., Gniezno, Poznań, Kraków).

Class Features & Skills

1. Lapidary Evaluation & Valuation (Level 1)

The Gem-Cutter can instantly identify any gemstone, precious metal, or mineral, determining its weight, purity, market value, and origin.

• Mechanic: A successful Intelligence Check reveals whether a stone is raw, synthetic/glass, or genuine, as well as its precise monetary value in silver denarii or gold solidus. On a Critical Success, the Gem-Cutter identifies any hidden astrological aligned traits or magical potential embedded within the stone.

2. Astrological Gem Attunement (Lithomancy) (Level 1)

In accordance with medieval lapidary lore, every gemstone corresponds to planetary spheres, zodiac signs, and spiritual resonances. A Gem-Cutter can cut, polish, and set stones to channel passive protective or enhancement effects for the wearer.

• Preparation: Setting a stone into a ring, amulet, or weapon pommel takes 1 day of meticulous work with fine tools and an expenditure of 10% of the gemstone's base value in materials.

• Attunement Cap: A character can only benefit from a maximum of 2 attuned gems at a time (or 3 if wearing a custom-forged Gem-Cutter's Crown/Pectoral).

Medieval Lapidary Resonances Table

Gemstone	Astrological / Symbol	Attunement Effect
Amber (Jantar)	Sun / Baltic Protection	+2 to Saving Throws vs. Sorcery, Evil Spirits, and Disease.
Garnet	Mars / Courage	+1 to Attack Rolls in melee; wearer is immune to Mundane Fear.
Sapphire	Venus / Purity & Law	+2 to Saving Throws vs. Poison; grants Advantage on Social/Negotiation rolls with clergy and nobility.

Ruby	Sun / Vitality	Increases maximum Hit Points by +4 while worn.
Jet / Onyx	Saturn / Ward	Reduces all incoming physical damage by 1 (minimum 1).

3. Prism Focus & Light Channeling (Level 3)

By focusing light through a flawlessly cut prism or high-carat diamond using specialized brass focus-mirrors, the Gem-Cutter can direct blinding or burning beams of light.

• Blinding Flash: Once per encounter, the Gem-Cutter can reflect available torchlight, daylight, or firelight through a gemstone. All enemies within a 15 ft. cone must make a Saving Throw vs. Hazards/Paralyzation or be blinded for 1d4 rounds.

• Solar Focal Ray (Level 5): When operating in full daylight or near a major open flame, the Gem-Cutter can channel a focused heat beam: Range 30 ft., deals 2d6 Fire damage (Attack roll required using Dex).

4. Socketing & Imbuing Artifacts (Level 6)

At 6th level, the Gem-Cutter learns the secret medieval art of carving binding runes and micro-facets onto precious gems to store magical power or holy blessings.

• Spell/Miracle Storage: The Gem-Cutter can prepare a gemstone to hold a single 1st–3rd level Christian Miracle or Pagan Spell cast by an allied Cleric/Boginki practitioner. The spell remains trapped within the gem until shattered or activated as an action by anyone holding the gem.

• Gem Shatter: A character holding an imbued gem can crush it as an instant action to cast the stored spell/miracle immediately without failure checks. The gem is permanently destroyed.
