The Bloodthorn is a sinister, ornate dagger with a curved, leaf-shaped blade that gleams with a dark crimson hue, suggesting its bloodthirsty nature. The blade is intricately engraved with thorny vine patterns that seem to pulse with a faint magical glow, while the hilt is wrapped in black leather with silver filigree accents, culminating in a blood-red gem set at the pommel. The weapon exudes a menacing aura, with subtle particle effects of swirling red mist around the blade edges.
