Incendiary Grenades!

I felt like making an incendiary grenade. Then I realized that they were not different enough from molotov cocktails to deserve inclusion. But then I had the idea to make them release a airborne incendiary (white phosphorus or something similar)  to make them somewhat more powerful and interesting that molotov cocktails.

And  this is what I came up with. May or may not be slightly OP. 

May or may not be a decent implementation of white phosphorous..
