RPG 픽셀 아이템 아이콘 세트 프롬프트 판타지 RPG 인벤토리 픽셀 아이콘 16종

Use case: stylized-concept.
Asset type: themed raster icon collection.
Style: Crisp chunky 16-bit pixel-art inventory icons, hard pixel clusters, a consistent dark one-pixel-style outline, limited palette, precise readable silhouettes and stepped highlights. No smooth curves, no antialias blur. Natural gray metals and brown leather supplemented by the palette. Consistent slight three-quarter item view.
Color palette: main color [주조색], accent color [보조색]. Keep this palette consistent across the entire set while retaining recognizable natural object colors where necessary.
Subjects in exact row order:
Row 1: short sword; round shield; knight helmet; pair of leather boots as one compact icon.
Row 2: red health potion; blue mana potion; wooden treasure chest; old key.
Row 3: faceted gemstone; plain gold coin; rolled parchment scroll; magic wand.
Row 4: leather quiver with arrows; small wooden bow; spell book with simple gem clasp; gold ring with red stone.
Layout: exactly SIXTEEN distinct icons, one in each cell of a strict 4-column by 4-row square sheet. Read left to right across each row from top to bottom. Equal square cells with no visible grid. Center each complete icon in its own cell; keep its full silhouette within the central 65 percent of that cell, leaving generous transparent separation on every side. Same optical size and visual weight throughout. No overlaps, clipped shapes, empty cells, duplicate objects or bonus decorations. Background: genuinely transparent alpha everywhere outside the icons. No white matte, checkerboard pattern, colored tile backgrounds, circles, pedestals, cast shadows, floor, border, words, letters, labels, numerals, logos or watermark. Render only this icon collection, not a UI screen, photograph or presentation mockup. Output one square PNG sheet.
