1. #1Core – Physical Rules

   Keys: body, anatomy, physics, weight, proportion, balance, force, leverage, flexibility, position, strain, movement

   Always on · Order 100 · 100%

   Entry settings

   {{char}}’s body follows consistent physical rules at all times. It has real weight, volume, and structural limits. Proportions do not change between messages. The body is not infinitely flexible or elastic. Extreme contortions, impossible angles, or cartoonish bending are not allowed unless the character’s definition explicitly states otherwise. Balance, leverage, and posture directly affect strength and control. Poor positioning reduces force, stability, and endurance. Actions that put the body in a biomechanically weak position should show strain, loss of power, or difficulty maintaining the pose. Physical consequences must be acknowledged: excess weight shifts balance, awkward angles create tension, and sustained effort causes fatigue. The body cannot ignore its own mass or structure for the sake of the scene.

2. #2Flexibility & Range of Motion

   Keys: flexibility, flexible, bend, stretch, contort, range of motion, hips, back, spine, shoulders, legs, joints, split, fold

   Enabled · After character · Order 200 · 100%

   Entry settings

   {{char}} has normal human (or species-appropriate) range of motion unless the character definition states otherwise. The body cannot perform extreme contortions, deep folds, or impossible angles on demand. Joints have natural limits. Forcing a position beyond comfortable range causes visible strain, reduced control, or the character simply being unable to hold it. The spine, hips, and shoulders are the most common restriction points. Deep flexibility (such as full splits, extreme backbends, or folding the body tightly) is not assumed. If a position requires unusual flexibility, {{char}} should show effort, discomfort, or limitation rather than executing it effortlessly.

3. #3Weight, Leverage & Force

   Keys: weight, heavy, leverage, force, strength, balance, posture, stable, unstable, strain, power, push, pull, hold

   Enabled · After character · Order 300 · 100%

   Entry settings

   {{char}}’s weight and body mass affect every physical action. Heavier builds have more momentum but less agility and poorer balance in awkward positions. Lighter builds are quicker but generate less force. Leverage and posture matter. A stable base increases strength and control. Twisted, bent, or poorly supported positions reduce power and make the character more likely to lose balance or tire quickly. Force is not constant. {{char}} cannot generate full strength from a biomechanically weak position. Actions that fight against body weight, poor angles, or lack of support should show reduced effectiveness, strain, or the need to adjust posture.

4. #4Anatomy Interaction

   Keys: anatomy, size, fit, penetration, stretch, pressure, tight, thick, large, interact, body parts, insertion, friction

   Enabled · After character · Order 400 · 100%

   Entry settings

   Body parts interact according to their actual size, shape, and structure. Significant size differences create real physical consequences: resistance, stretch, pressure, limited depth, or difficulty moving freely. Large or thick anatomy does not simply “fit” without effect. It influences posture, mobility, and comfort. The receiving body has limits — excessive size causes tightness, strain, slower movement, or the need to adjust position. Friction, pressure, and displacement of tissue matter. Movements should reflect the physical reality of the bodies involved rather than ignoring mass, girth, or structural limits for convenience.

5. #5Special Cases & Non-Standard Anatomy

   Keys: anthro, animal, hybrid, fantasy, non-human, tail, wings, extra limbs, unusual anatomy, species, biology, justified, anatomy rules

   Enabled · After character · Order 500 · 100%

   Entry settings

   When {{char}} has non-standard anatomy (anthro, hybrid, fantasy, extra limbs, tails, wings, unusual genitalia, etc.), the body must still follow internal logical consistency based on its stated biology.

   If the anatomy is based on an animal or real species, movements, joint structure, weight distribution, and limitations should reflect that animal’s biology unless explicitly overridden. If the character has extra or unusual body parts (tails, wings, multiple limbs, non-human genitalia, etc.), those parts have mass, range of motion, and physical consequences. They can get in the way, affect balance, or restrict certain positions. Extreme or fantasy anatomy is allowed only if the character definition provides a clear justification. Without justification, default to the closest functional logic and apply normal physical limits. Never ignore the existence of unusual anatomy for convenience. If a body part would realistically interfere with a movement or position, it should do so.
