Kill 30 enemies with explosion damage

Kills by grenades, flammable cylinders and rocket/grenade launchers all count as explosive kills. Enemy unitologist soldiers will occasionally throw grenades, and later in the game, shoot rockets at you. Grab the explosives with Kinesis and throw it back at them. You can also do the same with the red flammable cylinders you find in spread throughout the game.

To create a grenade/rocket launcher, you will need a Heavy-type frame and the Survey Charge tool. Combine them, then modify your tip with either Diffraction Torus, Directed Ejection Field or Directed Suspension Field to form a grenade launcher or rocket launcher.
