The Large Charm of Inertia is a mystical talisman with a dark, metallic base, intricately engraved with arcane symbols that pulse with a faint, eerie glow. Its surface is smooth yet slightly weathered, suggesting ancient origins, and it features a central, swirling vortex design that seems to absorb light. The charm is roughly the size of a palm, with a weighty feel, and its edges are lined with small, jagged runes that enhance its ominous presence.
