Jackal

root@dahl-db:~$ cat description.txt

A Dahl SMG with a fixed-element Maliwan barrel, giving it unusually strong elemental damage over time and a high status chance for its rarity. Because its parts are locked, it drops less often than its color suggests, but its reliable elemental procs can keep it useful for a long time while leveling.

root@hyperion-db:~$ cat notes.txt

Other Dahl SMGs in the same fixed-element group include the Beetle, Eel, and Scorpion. It only appears at green rarity or higher and is a random world drop from suitable loot sources.
