Geomancer

Arcane power lies dormant within the crystalline lattice of stone. Since the world’s formation, minerals have trapped elemental force, pressure, memory, and motion within their structured matrices. Most see only rock and ore. You perceive the imprisoned energy within.

 

Through carved sigils, attuned gemstones, and fractured geodes, you unlock these mineral matrices and release the power sealed inside. Jasper yields elemental fury. Obsidian carries volcanic wrath. Lodestone hums with geomagnetic force. Each stone is a key, and each key reshapes the battlefield in a different way.

 

Your magic does not simply summon flame or thunder from nowhere—it frees what was already bound. Stone rises to shield allies. Pillars of earth erupt like spears. Living constructs take shape from fractured shale. Metal trembles under magnetic command. Even the ground itself bends, cracks, and shifts at your direction.

 

To be a geomancer is to understand that power is never created—it is uncovered, unlocked, and unleashed.

 

Level 3: Mineral Matrix

Beginning at 1st level, you unlock the arcane forces sealed within crystalline matrices and rare minerals.

 

At the end of a long rest, you may attune to one mineral matrix from the list available to you. While attuned, you gain that matrix’s benefits. You can only benefit from one matrix at a time at 1st level.

 

You gain additional Matrix Slots as you gain levels in this class:

 

• 6th Level: Two matrices active
• 14th Level: Three matrices active
• 18th Level: Four matrices active

 

 

You may change one active matrix whenever you finish a long rest.

 

Beginning at 14th level, you may replace one active matrix during a short rest by spending 3 sorcery points.

 

Each matrix represents a unique mineral lattice that releases a specific arcane effect while active.

You unlock the elemental structure sealed within jasper’s crystalline lattice.

 

You gain a +1 bonus to damage rolls of your sorcerer spells.

 

Additionally, when you cast a sorcerer spell that deals damage, you may change its damage type to bludgeoning. The spell’s damage type is replaced with the chosen type for that casting.

Beginning at 3rd level, your attunement to crystalline matrices grants you access to additional spells. You learn certain spells when you reach specific levels in this class, as shown in the Geomancer Spells table.

 

Each spell counts as a sorcerer spell for you, and it doesn’t count against the number of sorcerer spells you know.

 

Level 6: Earth Spear

Starting at 6th level, you can hurl a jagged lance of stone at your foes.

 

As an action, choose a creature you can see within 60 feet. A spear of stone erupts from the ground and strikes it. The target must make a Dexterity saving throw against your spell save DC.

 

On a failed save:

 

• The target takes 3d8 bludgeoning damage
• And is knocked prone.

 

 

On a success:

 

• The target takes half damage
• And is not knocked prone.

 

 

After the spear strikes, shattered stone scatters across the ground in a 5-foot space beneath the target, which becomes difficult terrain until the start of your next turn.

 

You can use this feature a number of times equal to your proficiency bonus, regaining all expended uses when you finish a long rest.

The slab grants the target total cover against the triggering attack, potentially causing it to miss.

 

The slab occupies a 5-foot space and remains until the start of your next turn, after which it crumbles into difficult terrain.

 

You can use Reactive Rampart a number of times equal to your Charisma modifier, and you regain all expended uses when you finish a long rest.

• Rupturing Presence. The ground in a 20-foot radius around you is difficult terrain for your enemies.

That creature must succeed on a Dexterity saving throw against your spell save DC or take 2d8 bludgeoning damage and fall prone. A creature that succeeds takes half damage and isn’t knocked prone. A creature can only be affected by this rupture once per turn.

 

Earthquake Sovereignty. While in this state, if you cast Earthquake, you can choose a number of creatures up to your Charisma modifier to be unaffected by the spell.
