Conjure Darkfire

You conjure a type of magical flame from the Shadowfell called darkfire at a point within range. Unlike normal fire, darkfire does not shed light but instead drains nearby sources of light and darkens an area. The flame you conjure casts Darkness in a 20-foot radius and Dim Light for an additional 20 feet. Darkfire is faintly visible and ghostly-white at the center and rises into inky black flames.
