The Astral Spike Fragment is a jagged, irregular shard of otherworldly material, glowing with an eerie, pulsating light. Its surface is smooth yet fractured, with sharp edges that seem to defy conventional geometry, reflecting the game's surreal aesthetic. The fragment emits a faint, shifting hue, transitioning between deep purples and blues, suggesting its origin from a dimension beyond our own. Its core appears semi-translucent, with swirling patterns that hint at contained energy or unknown properties.
