CURSE TOOLS~
.
1. Archer of Distance
Grade: Special Grade (Technique-Responsive Weapon)
Form: Saber
Core Effect
.
The saber reads and traces the spatial "path" left by an opponent's cursed technique and counterattacks along that exact pathway.
The faster the incoming technique traveled
The more refined the technique
→ The faster and more lethal the counterstrike becomes
.
This includes:
Projectile CTs
Linear domain techniques
High-speed movement techniques
Certain teleport-style CTs if they leave a spatial trace
How It Works
Every cursed technique disturbs space and cursed energy flow
Archer of Distance records the trajectory
The saber then collapses space backward, striking through the same vector
Think of it as space being "rewound" only along the technique's path.
Scaling Rules
The weapon does not generate power on its own.
.
Damage & speed depend on:
User's cursed energy output
User's physical body
User's perception and reaction speed
A weak sorcerer can't abuse it.
Strengths
Perfect against speedsters
Punishes reckless CT spam
Extremely effective in duels
Can bypass defenses by following a "known path"
.
Limitations (Very Important)
Cannot activate without a detected technique
Ineffective against purely physical attacks
Cannot work on a domain sure-hit effects
If the user can't react in time, the tool is useless
Special Technique (Optional)
"Reverse Trajectory Severance"
A single-use swing that cuts the spatial path itself, temporarily damaging the opponent's technique accuracy .
.
2. Time Sacrifice
Grade: High Special Grade
Form: Dagger
Core Effect
The user sacrifices lifespan to force the body back to a prior "healthy state."
.
Healing speed depends on life sacrificed
The user chooses how much time to give up
Healing ignores:
Soul damage
Organ destruction
Nervous system failure
Poison
Curse corrosion
If the body ever existed in a functional state → it can be restored.
.
What Makes It Special Grade
This is not RCT.
Temporal self-reversion
The body is "rolled back" using cursed energy bound to time
Costs & Restrictions
Lifespan is irreversible
Excessive use causes:
Aging acceleration
Curse energy lag
Reduced regeneration efficiency over time
A sorcerer who abuses it may look young but die decades early.
.
Limits:
You cannot heal past your birth
You cannot restore lost lifespan
If lifespan reaches zero → instant death
.
3. Will of Samsara
Form: Pendant
Origin: unknown special grade Curse object ,Dropped after defeating a Semi Grade 2 Spider Curse
.
Classification: Dormant Evolutionary Curse Object
This is the most dangerous one long-term.
Known Properties
.
Responds to:
Prolonged cursed energy exposure
Blood
Near-death experiences
Gradually adapts to the user
Alters itself based on the user curse technique and on what nearly kills the user.
.
Hidden Ability: Forced Evolution
The pendant:
Records trauma
Records technique exposure
Records physical limits
Then mutates itself or the user to prevent future failure.
.
Examples of Evolution Paths
If the user almost dies to fire → heat resistance
If the user loses to speed → neural acceleration
If poisoned → internal curse filtration
If overwhelmed → cursed energy efficiency increase
But all within the limits of the users body and curse technique.
The evolution is not guaranteed to be beneficial.
.
Risk Factor
The pendant may:
Rewrite instincts
Alter cursed energy nature
Slowly overwrite the user's original fighting style.
