Rain of Oblivion
From Halopedia, the Halo wiki
The Rain of Oblivion is a named variant of the T-57B carbine, upgraded with a fully automatic firing mode and faster rate of fire. It uses the T-57B's model but with a new yellow color scheme broken up by white and red stripes and Sangheili glyphs.
Halo 5: Guardians
The Rain of Oblivion is an Uncommon Level 3 Power Weapon REQ variant of the Carbine that grants 75 REQ Points when sold. It operates similarly to a normal Carbine but unlike many other precision weapons in the game, it can be fired in full auto and has a faster rate of fire, making it effective as a close-quarters precision weapon. As it has the same damage output as a Carbine, it scores a Perfect Kill on a full shield, full health Spartan with 7 rounds, which, coupled with the faster rate of fire, makes the Rain of Oblivion a faster-killing weapon than the Blood of Suban. A downside to its fully automatic operation is that it has a lower Smart-Link red reticle range than the other Carbines, making it less suitable for long-range engagements.
