The Echo Sabre is a semi-realistic fantasy weapon featuring a sleek, double-edged blade with a slight curve, resembling a traditional sabre but with magical enhancements. The blade is made of a dark, metallic material with glowing blue runes etched along its length, suggesting its magical properties. The hilt is wrapped in dark leather, providing a secure grip, and is adorned with a small, pulsating crystal at the pommel, which emits a faint blue glow, indicating its ability to echo attacks.
