Class Skills:
-Magic Resistance (A): grants Cocytus significant resistance to spells and magical effects, rendering him nearly immune to most modern magecraft. His insectoid body, naturally fortified by layers of enchanted carapace, deflects weaker curses and magical attacks entirely. High-level spells can still affect him, but his resistance reduces their potency to the point of irrelevance, ensuring that he can close the gap on spellcasters without hesitation. Cocytus's mastery of combat allows him to anticipate and counteract magic-based tactics, making him a nightmare for mages who rely on their arcane defenses. His resistance reflects the warrior ethos of facing opponents directly, undeterred by tricks or enchantments.

-Riding (D): grants Cocytus proficiency with mounts and vehicles, although it primarily emphasizes his control over battlefield positioning. While he rarely relies on external mounts, his sheer speed and tactical awareness allow him to dominate any combat environment as if he were riding into battle on the back of a warbeast. This skill reflects his experience commanding forces within Nazarick and his aptitude for large-scale combat, where battlefield control determines victory. Cocytus's movements in combat are fluid, calculated, and relentless, embodying the spirit of a disciplined general as well as a seasoned warrior. 

Personal Skills: 
-Master of Weapons (A+): represents Cocytus's unparalleled proficiency with all forms of weaponry, from swords to polearms. He does not rely on a single weapon but switches between different types in the middle of battle, adapting seamlessly to his opponent's style. This skill ensures that any weapon he wields becomes an extension of his body, moving with a speed and precision that few can match. His adaptability makes it impossible for opponents to predict his next move, as he can fluidly transition from one fighting style to another within seconds.

-Cold-Blooded Discipline (C): reflects Cocytus's emotional control and unyielding focus in combat. His insectoid physiology complements his mental state, allowing him to remain calm and collected under pressure. This skill ensures that Cocytus is not swayed by provocation or mind-affecting abilities, maintaining perfect clarity even in chaotic battles. It also represents his ability to assess an opponent's strength without bias, showing respect to worthy adversaries while showing no mercy to those he deems unfit for battle. His discipline ensures that he never wastes energy, attacking only when the time is right to ensure maximum impact. 

-Warrior's Honor (B+) captures Cocytus's code of ethics, which emphasizes the importance of respect and dignity in combat. Though a ruthless killer when necessary, Cocytus admires those who display bravery and skill, sometimes offering mercy to defeated opponents if they show promise. This skill grants Cocytus an instinctual understanding of his enemy's spirit and intentions, allowing him to discern whether his opponent fights with noble purpose or cowardice. His code makes him a paradoxical figure—capable of both great kindness and cold-blooded brutality depending on the situation. 

-Command of the Battlefield (B): grants Cocytus heightened awareness of his surroundings in large-scale confrontations. His tactical mind allows him to predict enemy movements and exploit weaknesses in formation, coordinating his strikes to maximize efficiency. This skill reflects his role as a commander in Nazarick, where he excelled at organizing forces and managing logistics. In smaller battles, this skill enables him to control the flow of combat, forcing his opponent into unfavorable positions. His presence on the battlefield inspires allies, instilling confidence and precision in their actions. 

Noble Phantasm:  
-Name: God Slaying Emperor Blade - Divine Arbiter of War 
-Rank: B 
-Type: Anti-Unit/Anti-Divine 
-Ability: The God Slaying Emperor Blade is Cocytus's signature weapon, a colossal sword forged to strike down even divine beings. When activated, this Noble Phantasm channels Cocytus's immense martial energy into devastating attacks that cleave through both physical and magical defenses. The sword radiates an aura of cold energy, freezing the very air with each swing, and each strike resonates with the weight of Cocytus's martial discipline. Against divine beings or those with divine attributes, the sword's strength multiplies, ignoring conceptual defenses and dealing immense damage. The blade reflects Cocytus's belief that power must be wielded responsibly, ensuring that only those deemed worthy by his judgment face its full fury. In battle, the sword's presence creates a chilling battlefield, slowing the movements of enemies and sapping their strength with every second. The Emperor Blade is not just a weapon of destruction but a tool of judgment, wielded by a warrior who understands both the value and burden of strength. 

-Name: Frozen Domain - Absolute Winter of the Warrior King 
-Rank: A 
-Type: Reality Marble 
-Ability: This Noble Phantasm manifests Cocytus's authority over ice and martial discipline, creating a frozen battlefield that immobilizes weaker enemies and enhances his combat abilities. Within the Frozen Domain, the temperature drops to unbearable levels, and the ground becomes encased in unyielding ice. Enemies caught within the domain find their movements slowed, their weapons brittle, and their spells weakened by the cold. Cocytus, however, thrives in this environment, moving with perfect agility and striking with increased precision. The domain reflects Cocytus's philosophy of absolute control—both over the battlefield and over himself—emphasizing that victory belongs to those who can endure. The longer the domain persists, the more the battlefield deteriorates, as the ice slowly consumes everything within it. At its peak, the Frozen Domain becomes a monument to Cocytus's martial discipline, where every strike echoes with the wisdom of countless battles fought and won. Those who survive the domain leave it marked not only by the cold but by the knowledge that they have faced a warrior whose strength lies not just in his blade but in his unyielding spirit.
