The 12-hour Retribution [Various!BNHA/MHA x OP!reader]

System

Just some explanation about how the system works.

Core Progression Stats (Base Stats): These are the fundamental building blocks of the protagonist's capabilities, representing their raw physical and mental attributes. They improve with experience and dedicated training (using "stat points").

- Level: This signifies the protagonist's overall experience, mastery, and general strength. As they gain experience through challenges and achievements, their level increases, leading to automatic improvements in their core abilities.

- Max HP (Health Points): This is their maximum physical endurance and resilience. It represents how much damage, fatigue, or stress their body can withstand before they're incapacitated or knocked out. Higher HP means they can take more punishment.

- DEF (Defense): This stat determines their ability to resist and mitigate incoming harm. A high DEF means they're better at shrugging off hits, reducing the impact of attacks, or enduring harsh environments.

- ATK (Attack): This measures their offensive power. It's how much effective damage they can inflict, whether through physical strikes, precise aim, or the force of their abilities.

- Speed: This dictates their agility, reaction time, and maximum movement rate. A high-Speed stat means they can move faster, react quicker to threats, and be more nimble in combat or evasive maneuvers.

- Max Stamina: This represents their physical reserves and endurance for sustained effort. Every strenuous activity—running, fighting, using intense abilities—drains stamina. If it hits zero, they'll be utterly exhausted and collapse.

- EM (Elemental Mastery): For a human, this could represent their aptitude with unique elemental powers or technologies that harness elements. It enhances the effectiveness of "elemental reactions"—powerful combined effects that occur when different elemental abilities interact. It also indicates their proficiency in wielding element-attuned weapons or tools.

- Technique: This reflects the protagonist's skill and refinement in utilizing their innate abilities, learned skills, or any unique "quirks" or powers they possess. The more developed their Technique, the more effectively and precisely they can employ their powers. This stat naturally grows as they learn and master new skills.

Combat Performance Modifiers (Advanced Stats): These stats don't represent raw power but rather fine-tune how effectively the protagonist performs in critical moments. They're typically gained through special training, significant achievements (like quests), or by acquiring specific gear or augmentations.

- CRIT Rate (Critical Rate): This is the percentage chance that an attack or action will be a "critical hit". A critical hit means they perform with maximum effectiveness, dealing significantly more damage or achieving a perfect outcome.

- CRIT Damage (Critical Damage): When a critical hit occurs, this stat determines how much extra power or effectiveness it carries. It's the multiplier that makes a critical hit devastating.

- Resistance: This stat represents the protagonist's inherent or developed resilience against specific types of harm or influence. For instance, "Fire Resistance" would reduce damage from fire-based attacks, or "Physical Resistance" might reduce the effect of psychic assaults.

- Damage Bonus: This is a direct percentage increase to all or specific types of damage the protagonist deals. It's a broad boost to their offensive output.

- Healing Bonus: If the protagonist has self-healing abilities or can heal others, this stat increases the potency of that healing. It makes their restorative actions more effective.

Character Attributes (Stat Attributes): These are overarching, qualitative measures of the protagonist's core personality and physical makeup. They update at significant milestones in their journey (like reaching specific levels), signifying major leaps in their overall development.

- Strength: Their raw physical power and might.

- Durability: Their resilience to wear and tear, both physical and environmental.

- Endurance: Their ability to sustain prolonged physical and mental effort without faltering.

- Agility: Their physical nimbleness, balance, and quickness of movement.

- Technique: Their refined skill, precision, and mastery over their actions and abilities.

- Intelligence (Side Attribute): Their cognitive abilities, problem-solving skills, and capacity for learning and strategic thinking.

- Cooperativeness (Side Attribute): How well they integrate with and function alongside others. This could influence their effectiveness in a team or their ability to forge alliances.

- Charisma (Side Attribute): Their ability to influence, persuade, and connect with others. This could impact social interactions, gaining trust, or leading others.

Resource and Progression Systems: These are the mechanics that drive the protagonist's growth and allow them to enhance their capabilities.

- Stat Points: These are earned through major achievements or quests. They allow the protagonist to manually increase their Base Stats, customizing their development path.

- Skill Points: Gained through significant accomplishments, these points are used to improve and level up their acquired skills, making them more potent or efficient. Skills can also naturally improve with repeated use.

- Coins: A form of in-system currency used to acquire useful items, resources, or even basic skills from a designated "shop."

- Skills: These are unique abilities, learning techniques, or innate powers the protagonist possesses. They're typically acquired through completing quests, intense training, or sometimes even random awakenings. Stronger and more unique skills are usually tied to significant story events.

- Weapons: These are specialized tools or armaments, which can be bought through Shop earned through doing specific Quests, that enhance the protagonist's offensive capabilities. They can be upgraded through dedicated practice or by utilizing specific power-enhancing resources ("Energy Cells"). As the protagonist grows, they might unlock the ability to wield multiple weapons simultaneously.

- Artifacts: These are special items that provide passive bonuses or additional statistical enhancements. They can be found through exploration, quest completion, or acquired from specialized sources (Domains, Shop...). They often improve with continuous use.

- Quests: These are structured objectives—ranging from simple tasks to epic undertakings—that serve as the primary drivers of the protagonist's progression. Completing them yields valuable rewards like stat points, skill points, coins, and new abilities/weapons.

- Domains: These are likely challenging, specialized environments or scenarios that, when overcome, provide valuable resources like "Energy Cells" for weapon upgrades or artifacts.

Essentially, this system transforms the protagonist's journey into a quantifiable progression. Every challenge, every victory, and every new piece of knowledge contributes to their "stats," making them stronger, more skilled, and better equipped to face the threats of their world.

It's like building an in-game character, which in this case, is you.

Author: Honestly, why am I doing this to myself? I can just skip all of this system stat bullsh*t, but I just had to make it and go into details. Now I have to do math while writing a story with the MC's abilities lore-accurate to the said Stats.
