One of my first DOT weapons that I'm still using to this day, the heat will stack and eat up everything inside the large cloud and the viral will make things go faster.
Combine this weapon with traps or crowd control abilities and you will have an easier time killing them off with your other weapons.

That's right, this is a DOT weapon after all, it doesn't really kill the enemies for you, it only marinates them. It is a good secondary option to use with a [Vigorous Swap] build for example.
