The Stimulating Sigil is a small, intricately designed emblem with a dark, pixel-art aesthetic, featuring eerie hand-drawn elements. Its shape is circular with asymmetrical, organic curves, resembling a twisted, glowing rune. The surface is textured with a rough, weathered look, and the sigil emits a faint, pulsating glow in a muted, eerie green hue, suggesting arcane energy. The edges are slightly cracked, as if aged by time, and the center bears a deeply engraved symbol that seems to shift when viewed from different angles.
