Eerie Bow

The Eerie Bow is a bow which holds a currently unknown significance. As the name suggests, it gives an uncanny feel to its user.

Sagitta is the original owner of the weapon, but he gave it to Lucius as a reward for defeating him in battle.

During your fight with Paronomazein, it was revealed that the bow has the very circumstantial ability to unlock one lock within the span of its existence. Lucius utilized this to assist you in your battle, getting through an otherwise impenetrable door.

Trivia

 * Its image is the maple shortbow in RuneScape.
 * The Eerie Bow isn't quite an official name; Sagitta gave it such a title for the sake of simplicity.
