Firefly amulet bug

Firefly bug

Tonight, I sat down with my buddy to help him through some maps. I'm playing Spark CI, and he's playing Inferno Witch. I started taking serious damage, and we couldn’t figure out why it was happening only when he used Firewall. After some investigation, we realized that his Firefly amulet was igniting my Spark, causing me to take massive fire damage. I was literally burning myself to death.
