Prometheus Lens

Prometheus Lens is an exotic solar Trace rifle in Destiny 2: Curse of Osiris. The weapon generates a field of intense heat the longer it is fired, and kills return a fraction of ammo spent (Around 1/3). The gun was originally shipped out in Curse of Osiris with a bug that increased its damage to kill noticeably faster than most other weapons, partially due to the solar damage field generated by the weapon. The bug is more noticeable and effective in PvP.
