Is this intended?
By the way this skill really could use a better description.
“Burning enemies have a small chance to explode on death”.
What small chance? Why not tell us exact chance %, like every other skill description do? Also, yes, they explode on death, why not continue: “staggering surrounding enemies” — or: “damaging surrounding enemies” — or: “damaging surrounding enemies and lighting them on fire” (dang, this skill would be awesome, then)?
