Guidelight of Oblivion

The Guidelight of Oblivion is a post-Moon Lord sentry dropped by Signus, Envoy of the Devourer. It is the rare variant of the Cosmilamp. It summons a soul lantern that floats up and down near the location it was summoned. The lantern summons red flames around it which home in on enemies, travel through tiles, and explode upon contact, inflicting the Brimstone Flames debuff for three seconds.
