- The user made an overview painting of the boss area in Gemini from a description Claude wrote (
01-concept/PROMPT_BossArena_Ploutonion.md). Saved as01-concept/MAP_Ploutonion_Mouth_painting.png; labelled versionMAP_Ploutonion_Mouth.png, also the boss area's loading screen (T_KeyArt_Loading_PloutonionMap). Ledger: Gemini's commercial-use terms marked CHECK before release. - The Maw: a crop of the painting → Meshy (SM_PolydegmonMaw, PR-49): the ring of bronze jars and bronze/bone arms on its disc, replacing the grey-box arch, vessels and hands; a round cold glow fills the ring; a glowing Greek-key ring (T_FX_Ring) marks the threshold's danger edge.
- PloutonionBuilder: a Landscape terrain whose cliffs rise outside the arena, gorge and hollow (boxes hidden, collision kept), Poly Haven rock faces along the walls, dark rifts with rock piles where the Received come out, the hearth's ring of stones, forest past the hollow. Cave grade lifted to grey-teal (exposure 1.2, saturation -14). The fight layout is unchanged.
