Burnerang enchantment?

Currently playing in the "All the mods" pack and just finished one of those "giant tower leading to 3-4 layers of progressively harder mobs" dungeons and as I was sorting through my book loots I found this enchantment "Burnerang". I googled all over and found nothing so I'm now turning to you guys. Do any of you know what the heck this enchantment is? PIC
