The Frost Giant's Frenzy Stone is a medium-sized, roughly hewn chunk of ancient glacial ice infused with the chaotic energy of the Frost Giants. Its surface is uneven and jagged, with deep blue hues swirling beneath a frosted, translucent exterior. Cracks and fissures glow faintly with a pulsating light, suggesting the contained power within. The stone is asymmetrical, with one side featuring crude, runic carvings that seem to writhe when viewed from different angles. The material feels cold to the touch, with a texture that alternates between smooth icy planes and rough, crystalline outcrops.
