Image: A professional internal game design documentation

Generated from: A professional internal game design documentation sheet — a gameplay system infographic, 16:9 landscape, for the stylized Nordic fantasy action game "Rune Warrior: Echoes of Ragnarok". OVERALL LOOK: dark blue-black UI panels with subtle carved Norse knotwork ornament, thin bronze/gold panel borders, small parchment accent notes, warm iron and leather tones, soft cinematic lighting, clean modern infographic layout with generous spacing, no clutter, crisp readable sans-serif body text with an elegant engraved serif for headings. AAA game design document aesthetic. Painterly stylized art, NOT photorealistic, no sci-fi, no neon. CHARACTER (identical in every panel): Eirik, a small chibi Norse warrior with slightly Zelda-like proportions — big head, compact body. Blond hair tied back, short light beard, thick grey fur collar, dark leather and iron armour, short sword, round wooden Viking shield with iron rim and a rune boss. Same face, same colours, same silhouette in all six panels. TOP LEFT TITLE BLOCK: Heading: "RUNE WARRIOR — STAMINA SYSTEM DESIGN" Subtitle underneath: "One resource. Multiple gameplay systems." Small line of body text: "Stamina is a shared, reusable resource — it powers shield blocking now, and runes, heavy attacks, dodging and sprinting later." TOP RIGHT — a panel headed "CORE VALUES", a neat two-column table of label and value: Max stamina — 100 Regeneration — 22 / sec Regen delay — 0.75 sec Shield hold — 8 / sec Blocked attack — 15 Exhaustion lockout — 1.0 sec MIDDLE BAND — a row of SIX illustrated gameplay-flow panels of equal size, numbered 1 to 6 in small bronze circles, each with a small painted vignette of Eirik and a compact stamina bar beneath it: 1. "SHIELD RAISED" — Eirik braced behind his raised shield. Stamina bar nearly full at 100, draining. Label: "Shield hold: −8 stamina / sec". 2. "ATTACK BLOCKED" — an enemy axe slams into Eirik's shield with bright impact sparks. Bar dropping. Label: "Blocked hit: −15 stamina", small text "92 → 77". 3. "STAMINA DEPLETED" — empty dark red bar reading 0, Eirik's shield drops automatically out of guard, tired posture, small red warning flash. Label: "Shield drops at 0". 4. "EXHAUSTION" — Eirik hunched and winded, cannot block, an hourglass icon beside him. Label: "Exhaustion: 1.0 sec". 5. "RECOVERY" — Eirik straightening up, a soft green refill glow on the bar and a green "+22 / sec" tag. Label: "Regen delay: 0.75 sec". 6. "READY AGAIN" — Eirik confident, shield raised again, bar full and blue at 100. Label: "Stamina restored — 100". LOWER LEFT — a panel headed "STAMINA HUD CONCEPT" showing five small compact Nordic stamina bars side by side, slim and stylized with a thin iron frame, sized to sit next to a health bar (small and restrained, NOT oversized MMO UI), each with a caption under it: "Full / hidden" (faded out), "Active use" (blue, partly drained), "Low — under 25%" (amber, nearly empty), "Empty / exhausted" (dark red, cracked, small warning pulse), "Regenerating" (green refill sweep). LOWER MIDDLE — a panel headed "COMPONENT ARCHITECTURE" with a clean node tree diagram, thin bronze connector lines: "Eirik (CharacterBody3D)" at the top, branching down to "StaminaComponent3D" (highlighted as the central authority with a glowing rune icon), "CombatController", "ShieldController", "RuneController (later)", and "HUD" which branches to a child "StaminaBar". A small caption reads: "StaminaComponent3D owns the resource — every other system spends through it." LOWER RIGHT — a panel headed "FUTURE USES" with six simple line icons in a row, each labelled: "Shield — now", "Runes — later", "Heavy Attack — later", "Dodge — later", "Sprint — later", "Other abilities — later". All text must be correctly and legibly spelled in English exactly as written above. Balanced grid layout, everything aligned, comfortable margins.
