A Grade Sword is a weapon forged around a single embedded pearl core.
Only one pearl can be used per weapon — any more will destabilize the forging resonance and shatter the blade.
The size of the pearl determines the sword’s Grade, while the type of pearl determines the attunement category:
Meito — Elemental Pearls
Kokuto — Blood Pearls (death-attuned)
Yoto — Siddhi Pearls (spiritual/martial)
Cursed — Broken or corrupted pearls that shouldn’t work but somehow do
Grade Swords are not named for forging method, rarity, or brilliance—
They are named for which type of pearl sits at their heart.
The pirate world classifies pearls strictly for this purpose.
The same pearl sizes from your world lore apply:
Tiny Pearl → Low Grade Sword
Small Pearl → Standard Grade Sword
Medium Pearl → High Grade Sword
Large Pearl → Great Grade Sword
Giant Pearl → Legendary Grade Sword
The sword’s body is forged around the pearl, not the other way around.
This makes forging an art that only Pearlwrights and Blacksteel Smiths can master together.
If the pearl is flawed, the weapon is flawed.
If the pearl is powerful, the weapon is devastating.
Now rewritten to fit your pearl classifications exactly:
Meito are the most visually striking Grade Swords, forged around pearls aligned with wind, flame, lightning, frost, pressure, or rarer elements like void or gravity.
The elemental pearl bleeds its nature into the blade.
A Meito “breathes” with the world’s elements — flame curls along the steel, frost dances across edges, lightning shivers beneath the surface.
Reliable elemental output
Safer to use than other attunements
Scales smoothly with wielder’s intention
Meito = Elemental Channeling, hybrid elements at higher levels, terrain manipulation, elemental finishers.
Kokuto blades are infamous.
Their pearls are formed from death-aligned energies: killing intent, battlefield trauma, violent storms, or ancient cursed graves.
When forged into a blade, they become hungry.
A Kokuto grows stronger the more blood it sheds.
Its steel deepens into obsidian black, reflecting accumulated death resonance.
They get sharper after every kill
They can reject unworthy wielders
They store kinetic and spiritual violence
Kokuto = physical augmentation, brutal finishing power, rage-driven resonance, shockwave attacks, death-aligned growth.
A Siddhi Pearl is created not by nature or death, but by human discipline.
Meditation.
Martial arts.
Breathwork.
Spiritual awakening.
Extreme clarity.
Pure intention in hardship.
Humans produce Siddhi pearls more than any other species — especially monks, assassins, martial masters, and sages.
When placed inside a blade, the sword becomes a conduit for inner power.
Yoto blades amplify:
Willpower
Technique
Martial arts
Inner abilities
Reality-altering cuts
A Yoto does not cut skin — it cuts concepts like intention, momentum, fear, weakness, or technique.
Yoto = Siddhi infusion, technique amplification, parries, reality-slice counters, high-skill playstyle.
Cursed pearls are mistakes of the world.
A pearl breaks — but does not die.
Its energy leaks, fluctuates, mutates.
Most smiths refuse to forge with them.
But when one succeeds, the result is a Cursed Grade Sword — a blade with unstable, often terrifying power.
Unpredictable element surges
Random power spikes
Can backfire violently
Whisper to their wielders
Develop personality akin to a parasite
Cursed = hybrid attunement, mixed abilities, unstable boosts, powerful but dangerous synergy.
A sword body can hold one pearl-core because:
Multiple resonance fields destabilize each other
Pearl energy requires a singular “flow path”
A blade’s spine can only channel one harmonic frequency
If two pearls are inserted, the blade will fracture like glass.
The sword’s Tier Level Boost comes entirely from the embedded pearl.
Larger pearls = more boosts to distribute.
Boosts enhance:
Power (Strength-based style)
Finesse (speed/agility)
Skill (reaction/technique)
Protection (defense/stability)
The wielder’s chosen Style determines how points are allocated.
