From Halopedia, the Halo wiki
The Dying Star is a named variant of the Z-250 DEEW, modified to fire adhesive pulsewave explosives. It uses the LightRifle's model, although the main body is now colored dark gray, broken up by orange and turquoise stripes flowing throughout the weapon.
The Dying Star first came into use during the Forerunner-Flood war, where the appearance of highly mobile and mutable Flood pure forms quickly led to Promethean countermeasures, with the Dying Star being considered as such. Another named Z-250 variant is the Barbed Lance, also used during the Forerunner-Flood war.
Halo 5: Guardians
The Dying Star is a Legendary Level 5 Power Weapon REQ that grants 200 REQ Points when sold. While functioning the same as a normal LightRifle, it fires adhesive pulsewave explosive rounds that can adhere to both infantry and vehicles and explode after 0.9 seconds. As few as three explosions deal enough splash damage to kill a full shield, full health Spartan. Unlike the other LightRifles, the Dying Star has the same rate of fire, whether hipfired or zoomed in. Although it has the smallest magazine size of the LightRifles (8 rounds), it makes up for this with its ability to deal major damage to infantry and vehicles due to its explosive rounds; it kills a Spartan in 3 rounds, whether hipfired, zoomed in, or with indirect splash damage. The Dying Star is most effective when used as a support or defensive weapon; other weapons like Barbed Lance, The Answer, and Blood of Suban are substitutes for offensive roles, as the player using the Dying Star may die before the final explosion needed to finish off an enemy goes off. Also, the Dying Star is plagued with increased vertical recoil and a lack of ammo, as it does not appear frequently in matchmade games. The Dying Star retains the same overall range as a LightRifle: 30.46 m (99.93 ft) in hipfire and 76.20 m (250.00 ft) with Smart-Link active.
In Warzone, Legendary Promethean Soldier bosses, such as Soldier Enforcers, may use the Dying Star; however, this particular Dying Star is glitched, as the game simply calls it a LightRifle and does not display a portrait for it when the player accesses a REQ terminal with the weapon picked up. In addition, it retains the regular LightRifle's 12 round magazine capacity.
