Black Clover

Because it's a mini-boss

Hi, I'm kinda new here and was exploring maps when one of my char got error because of and item from bifrost field. I checked the control panel and there's two unknown item in my inventory. Is there a possibility that I could get some help removing the items? 11547 and 4511 (The game crashes each time I try to log in my char) IGN: Silver Quiver Edit: Found the solution and fixed it by resetting position of my char then deleting the item using the forsaken kafra.
