Tattoo design on a young woman's forearm. Realistic crimson red lizard climbing vertically along a cold dark grey dagger. The dagger blade is pierced by, or intertwined with, pulsing mycelium threads (cordyceps-style infection). The mycelium looks like a spreading infection, organic veins creeping from the wound onto the skin. Mood: dark elegance, body horror aesthetic, but delicate. High detail, 8k, tattoo art style, sketch on skin texture
